Re: DANG. RECOIL.
I'm not great at explaining this, but there is a mechanic built into the game that aids quite a bit with recoil. It's usually referred to as aim smoothing. I'll assume you're on controller, which makes it a bit easier for me to explain. But it is not input specific, MnK works the same way.
The way it works, basically, is that when a small amount of smooth input from the right stick, recoil is greatly reduced. Strafing while shooting (you should always be doing this anyway), the small adjustments you are making to your aim will cause the mechanic to kick in and greatly (not entirely) reduce your recoil.
My final advice would be to remember that when controlling recoil, less is often more. There is a tendency to over-compensate when only a very small amount of input is necessary. Instead of helping, this makes it harder to control.
You're on the right track overall if you've gotten used to the recoil on several weapons already! It takes a lot of practice time to get good at handling recoil in Apex. The good part is that the recoil in Apex is extremely consistent - it follow the same exact pattern every time. Many other FPS games introduce randomized bloom/spread instead. Good luck!
