The armor effects in reach were badass. Like the lightning and grunt birthday party. They can add so much now to halo 5 it would be great. Could bring back the samurai sword from 3, and have so many more accessories to personalize your spartan.
Why were that taken out in the first place?
I always thought armor effect would be nice if some of them only took effect after a extermination, killtac, a killing spree or some thing like that. More like a 3 second animation effect that gloats your kicking butt.
