I'll give two tips with Loid: Nekros is your friend. As is just blitzing the initial Necramech, the Vault "Bonus" after the Necramech, then going straight back and starting over from the top. Once you no longer need a tier, don't look back.
Specifically: Nekros can drop additional matrixes and Necramech parts. Which are guaranteed drops per Necramech, versus fairly uncommon for follow-up Bounties (regardless of tier). The matrix tier and number of Necramechs present (thus the number of Matrix drops) both increase with higher level bounties, so whereas the first tier will barely yield 1-2k Reputation (due to 1-2 Matrixes), the third tier will yield 15-30k Reputation (due to 3-6 Matrixes, often with at least one successful Desecrate pop).
Nekros is admittedly one I was reluctant to put in my "stable" as back during my first 20+ ranks there was a player willing to play them consistently. He's currently the 'Frame in my "Weapon Grinder" loadout slot meant for fast leveling, as I had a spare Aura Forma (now THERE'S a mechanic I way overused as a paying player - the item that makes every Aura the "right" one for mod slot purposes in a single Warframe. Any 'Frame properly inducted into my "stable" has one. Non-paying players had, like, one chance to get that type of Forma so far without earning Platinum another way?).
Note that you're going to need at least 20 Grandmother Tokens as well for a Serishard Glass if you ever intend to max them out. After that, most of the stuff should be assorted junk from the progression trees.
Seriglass is also used for three weapon blueprints and I won't need it until the last rank otherwise, so yeah, I've got time for that one.
A group will be immensely helpful when running Isolation Vaults, if only because of how DE made Necramechs an enemy who're invulnerable except for three locations on their body (with all three locations being ones they actively make efforts to shield from you if Solo).
This is going to be one of those situations like the Ramparts in Sortie missions where they turn the parts faster than you can move around them, isn't it?
Anyways, as I was saying in the Vent thread, I got swarmed for three hours after putting the trade offers up on the Warframe Market. I've still got about 9 pieces to buy, but I basically ran out of trade orders for the day so I'm laying low until tonight where I'll finish this off.
There were a few etiquette things I noticed. Biggest thing is that people were sending the message and doing invites IMMEDIATELY, without waiting for a response or considering for what I was in at the time. That is something I actually consider rude, and during peak messaging swarm time those players got delayed while I dealt with people who were willing to let the other party talk.
The fact that people sell off pieces to other players when I don't respond immediately is just expected, people somehow manage to have worse patience than me (which is a miracle given what I stated over in the Vent thread). One of my sales and one of my buys went down the way they did specifically BECAUSE both sides had patience (what happened in both cases was that we got INTO THE DOJO just about to do the trade and the buyer had a freak connection issue - or in my case, a 2-second power brownout that delayed the trade by about 10 minutes in the end).
One of my buys (for a Pyrana piece I believe) was facilitated by a third party. As in, someone did the message, brought me into the dojo, and their friend is the one who had the piece. Caught me off guard, but I assume this is basically one of those language-interpreter situations as the actual person with the piece never said a word.
Overall, I've learned my lesson not to put more than 5 buy or sell orders, or 1 order for a really hot item either way, up on the Warframe Market as "visible" at once. And like I said... I'm probably going to be picky about what I put up for sale on that place. I might not worry about selling for 40 Platinum, but given I'm in a situation where I can actually respond to the coupons that come in on Daily Tribute sometimes I'm not going to obsess over getting a measly 5 Platinum for a piece. Plus I'm still in a spot where I value Ducats a lot more.
UPDATE: After two days of trading, I am finally, FINALLY caught up on all the Primes I've missed, and fully current. Pretty much any part that comes in, I can evaluate whether it's a sell or a Ducat item without having to worry about hoarding my own pieces. I will have Kitguns and Moas to grind for gilding and mastery rank. And I come out of this with more than enough Platinum to get a month of both resource boosters.
....which I will not be doing just yet. I may get small ones if I need them for the Matrices, but after the Necramech is acquired? I am slowing WAY down for a while. I have several goals: Steel Path, Liches/Sisters, Riven Mods (which means Sorties and getting Slivers when I have too many of the Lich keywords), Conservation (Ivara's gonna work most likely), and hoarding more Relics for the next wave. If we get a Double Resource weekend and I'm there for it, then it's time to get as much Kuva as I can, otherwise I hit that up sporadically.
I will NOT be grinding the Helene node to level up all the items I acquired, or even most of them. No, I plan to take them alongside my non-Steel-Path missions to level up now. The only things I'd consider using Helene for are Lich/Sister weapons (as I have to level those multiple times), and I will level Warframes there during those times (at least, the ones I have no plans to use).
Plan is to hit the game up for no more than an hour a day, not get upset if I miss a Sortie, and max out at 3 hours per day on a weekend. If that looks like a lot, in the last 2 weeks I've been playing for a whopping 61 hours. I'd be capping play at about 10 hours a week, or 20 hours for two weeks. So yeah, there's DEFINITELY a slowdown here, down to about a third of the time.
....oh, and I actually got INCREDIBLY lucky and managed to get all three Requiems (to make the rest of this make sense, I often call them "keywords") on the Kuva Tonkor lich on the second try. First try, the one keyword I knew didn't work as the start. I put it as the second, a keyword I've never had as the third, and put in one keyword that had only one use on its mod as the first. When the other players saw this go down, they thought I was using Oull (which, to be fair, I actually have two of that keyword, I just haven't used it yet).
I have 3 "defiled" keyword mods. One more and I'll transmute.
I still think 3 tries is a good lich standard unless they show up REALLY early. Settled for a Hind with the Electric element (Nova made this one) as the next one as I have a Riven for the Hind. Once I get this, I put an Impact weapon from the Sisters side (so Rhino gets to spawn a nemesis now) as my next nemesis and then I don't blitz that for a while. (EDIT: This turned out to be the Tetra. I REALLY wanted Arca Plasmor... but when I got two Flux Rifles and a Diplos, and am in the phase where I still need to get everything eventually? I'm not gonna whine too hard about it.)
This and a Necramech, that'll wrap up the blitz.
UPDATE 2: I ran a lot of Isolation Vaults. It turns out I not only have the parts to make Voidrig, thanks to getting the damaged parts with the last gasp of my resource booster I'm more-or-less at a point where I can build Bonewidow too. Because the vault I spammed was Tier 3, I MAY even have enough Matrices where I don't need to run Vaults, period.
"But Frosty, Bonewidow requires Cranial Foremounts, and the fish that drops those needs a bait that requires rank 4 Entrati!"
I got lucky. Daughter had some for sale for a small fee in Platinum. When you're that close, THAT kind of nudge is worth it. THIS is why you hold on to some chump-change Platinum whenever you can.
I WILL still need rank 3 to actually get Bonewidow's blueprint, but that's the only real hiccup there.
NOW I can slow down.
