I did say competitive Pvp which at this moment only consists on trials :P but the fact people change gear after flying in makes it all the more essential to be able to see their gear. For example if someone was using celestial nighthawk and you could tell (tbh it stands out quiet alot) then when they golden gun you could quite easily just run in with 1 guy and use his shot rather thn fleeing and being shot from behind (have seen teams do this many times)
