One thing that I started doing and it's helping me a lot is to shoot more in third person, instead of trying to go to iron sights or first person every time. Weapons are surprisingly accurate, specially when crouched and holding the RMB, and it makes you a lot more mobile while maintaining situational awareness. I basically just go for first person when I have a scope or am trying to shoot an enemy that's too far away.
This news really bums me out. I feel like most people that wrote off the game on the episodic format might have actually enjoyed it if they gave it a chance. While I understand why it might have turned some people off, it really did make for a better game and experience than if it got released in a regular fashion.
