i see more hand cannons and scout rifles than ARs these days, but most people are still running around with shotguns and fusion rifles. fusions are way too accurate for the range they possess (charge time means nothing). they need to increase spread on fusion rifles, adjust the special ammo crate spawns, and limit the max ammo in heavy weapons. by no means all the necessary changes, but the outstanding issues as far as weapons go.
the other day i killed 3 people grabbing heavy ammo and enough ammo dropped afterwards to kill each of them for the remaining 8 minutes (to be precise, around 16 shots). if i died, i'd just pick up another one of the packs, which stayed there the whole game.
