I like to nuke ^^
Simple answer: Because it ALSO prevents the admins from becoming demotivated, and eventually stopping to answer TTs at all.I'm sorry... but how does writing proper tickets help the fact that we have lazy admins to begin with...? You can post all you want about people not writing tickets right and asking them to follow a certain policy when doing so, but fact is people are still going to do it.
Now, if there were.. say, admins that did their job, and didn't wave the "@" around like badge and a life accomplishment, those tickets could be closed sooner and not a problem.
If you got a lot of crappy tickets all day which stop you from answering the proper ones you will lose a lot of motivation over time.
There's more than just one way of "gettin rid of lazy admins" you know. ;3
