haven't you guys mentioned sawnies?
is it possible to hit someone with autoaim with that thing? because it has quite a large spread and that RIGHT (what i mean right is direction) part of the spread might hit the player.
Sawnies suck terribly with autoaim/gamepad since they are running weapons and you definitely will have to lead aim (which the autoaim/gamepad is not capable off).
Combat shotgun in combination with autoaim works very good on not so experienced players though. Same for M4 on a distance and Tecs/Uzis for close sprayfights (as mentioned).
I dont play with controller but can you shoot run etc better with controller. I think NO
If you are used to move around using keyboard and mouse (from other games maybe), then that's the way to go in my opinion. Fact is, you have a much (!) better control over the camera with the mouse, which should mean you do better in fights aswell due to the improved view.
Only positive thing in terms of movement I experienced while using a gamepad is that I ran/swam (on foot, of course) slightly faster then most other players and I've been faster on a bmx bike. I guess you can mash that little button on the gamepad just faster then the spacebar on the keyboard. Don't know if that's correct but I always had that impression.
