The simple existence of Hayabusa means you are wrong:
You are not wrong tho.
Most helmets were trash.
You say that as if outside of ODST(and its variants) and like the Mark xxx.
Halo ever had actually good Helmets
343 atleast had a number you could choose from that were decent.
Even reach had a limited number of good helmets:
Halo 3
I prefer the Reach and 3 design aesthetic far more than what we have here and in 4.
