Honestly the time-to-kill changes literally don't matter with this ammo economy. People are just running around with shotguns...and why shouldn't they? One-hit weapons should be limited. Why not go with the ammo economy you guys had in D1? From what I remember, no body spawned with special. Special spawned a few times a round(like power does now), but if you pick it up, teammates near you will also get ammo. Heavy is a 1-2 time a game spawn, and it only goes to one person. That way there can be some kind of counterplay to these weapons. Go play a crucible match and count how many times you die to someone actually out playing you with a primary weapon.
