Not really, SMGs are accurate enough when moving as are assault rifles, and consider these will be firing constantly, and there will be five people using them at max strength, so that's a lot of bullets, the main use will be to get closer, not to kill people, but the bullets flying will allow you to do a small amount of damage, and being close will allow you to do more, and the charge regeneration means you can move on very quickly after having done so.
No no reloading, just bullet hose all the way unless you stop to aim. Alternatively, lock the accuracy at standing, regardless of stance or movement speed, and allow constant infinite ammo, so stopping doesn't help.
I'd hate it if my squad leader decided when to make my accuracy go to shit. I'd rather have a no-reload bullet hose which uses my total ammunition. This keeps it effective while not necessarily overpowered.
Mortars and rpgs use cycle time, not reloading. No luck there. On the other hand, how would you like to spam the shotty pistol? XD
You could do that I guess, but I can't see too many people spamming it if they could run out of ammo.
No reloading + shotty pistol = omgwant I think even my girlfriend would start having wet dreams about this.
