I actually like some of these ideas, this would also make it to where some of the other armors in the game actually have a point and are not just collectors items. Mostly you see Aura field, Electro frame, and Wedding dress because for the most part these are some of the best armors and are fairly easy to obtain. I think it would be a good idea to beef up some of the rarer armors to give them a bit of an edge or make them just as good as other armor.
Honestly if some of these changes were made I might actually decide to use these armors when zerking.
