The armor sets giving a bonus is a good idea but most of them need either buffs or reworks. The Techsec set so far is about the best I can think of. Letting your Kinetic weapons deal with the elemental shields, overshields, and other things to leave your engery and heavy slots for dps. The Bushido looks cool and its 4 piece bonus is cool but its second could use a little work. The Lustrous set is ok. All in all the idea is good but execution needs a bit more work.
