I didn't even need to use my wings... I mean, look :unless you were using your wings as weapons, or sucking enemies into the black holes i don't see how it would be "broke"
Jin excels at opening up black holes for both offensive and defensive combat style, and he always ends up giving his enemies a really bad time trying to either get close to him or away from him in the process. He can also control the wind to reinforce his destructive capability or aid his teammates.
+ Lord of Swords : Jin can shoot out metallic blades (silver in color and unbreakable) to attack enemies and block their attacks (physical only) from all direction using "Blade Black Hole". However, he can only do so within his sight (as in, only in front of him). His mastery over this technique has led to him being able to sends out blades instantly, wherever and whenever he wants, to slice, thrust, stab and pierce his enemies as he wants. He can send the blades with such force that can break through buildings in just a few hits. He can also pull up blades from below the ground while staying completely motionless to catch his enemies off-guard.
+ Tyrant of Chains : Same as his skills over the blades, but this time he uses "Chain Black Hole", which shoots out hooked chains instead. He can also whip the chains across entire battlefield and/or snatch his enemies and fling them away.
+ Astral Assaulter : This type of black hole has a white outline. It allows Jin to defend himself by completely absorbing non-physical attacks (a fire-ball, for example). The attack, when absorbed, will "charge" the black hole up, until there's a white cross at the center. At this point, Jin can send out from it a straightforward blast named Nanovatomic Blast (Nano + Nova + Atomic), which causes a violent nuclear-like explosion on impact (no such thing as "radiation", though). The blast of a fully-charged black hole is much more dangerous than the chain/blade-summoning attacks.
He can also charge the Ward Black Hole up by himself with his own Air Blades to bring out mass destruction as he wants.
+ Heart of The Wind : Jin has full control over element Wind, and is just as destructive and skilled as he is with his Blade/Chain Black Hole, if not even deadlier. Unlike his attacks with black holes, which have to be within his sight, he can sends out Air Blades, in form of crescent-like waves, everywhere he wants. The mere air pressure can slice through metals like sharp knives cutting through hot butter. In addition, he can sense the life-force of all living beings around him using the wind, allowing for more accurate attacks with his Air Blades.
