I wish that too. I would like it to have instant kill if he swings his arm at someone during a sprint.
Do real damage? Nah, but cause a serious flinch/knockback? Absolutely. I personally want a MAX suit that makes milk shakes though. Strawberry in the right arm - banana on the left.
i disagree about the instent kill swining the arm during a sprint. but i all for crushing someone against a wall for an instant kill.
Heck, just make MAX units 'tangible' to everything, like vehicles are- even if they don't deal damage, if they were to be able to push infantry with their charge, it'd be pretty cool, useful, and fun.
I'd be happy with an effect similar to a concussion grenade if you pass through enemy during a Charge.
