Welcome! Dont forget, we also have Kalt, Donner, and a rotation server. All are fun.
Recoil can be tricky. You will hear a few different responses, from burst fire, (recommended) to aiming at the crotch area and let the recoil raise you to center mass.
I bought a good mouse (Razer Death Adder 2013) I set the DPI as high as it will go (6400) and lowered the in game sensitivity to next to nothing. that way, its not too jumpy running around and looking around, but its there when you need it... for example, when you have to spin around quickly, or... recoil! I just draw my mouse down slightly and it stays in a pretty tight group.
Burst fire.. 3 or 4 shot bursts, will probably be your best bet.
See you out there! -Q
