why is there 30 damage automatic guns

[bloodykiller]

i use 6 hotkeys, strafe key, 4 directional keys, reload key, melee key, shooting key, grenade key, "F function" key, inventory key and some other keys i'm forgetting about just to pk, how would that work out on an ipad/iphone?
you guys say iera is better because you don't pk and don't realise how limited of an experience iera is for a skilled pker
