nah, when a guy can dance around with his bare fists and beat you when you're firing a weapon, ANY weapon, the aiming controls are not ok. That should not happen, ever. Not even if you're a newb to the game going against a seasoned pro.
this game was made to play with the precision of a mouse, and that just can't be done with the controller. Not debatable. While there are a select minority who have the hand dexterity to better approximate that type of precision, the majority of us are left with a herky-jerky mess where it's nearly impossible to realign the reticle on a target that hops or zigzags within an easy 50 meters. So while that may be fun for a few, the majority are left in the cold.
I think they should at least explore adding a mode with limited aim assist, something like where there isn't any outside of 50 meters but within that 50 meters, the closer you get the greater the assist. So when you get to point blank with a shotgun there is no doubt you aren't going to get punched to death.
Sounds like you just need to practice more. The aiming has gotten better. If this game is too difficult I suggest playing a more casual shooter.
