I always use the control, though play on PC. I find it very comfortable and I understand that the aim assistance is a fair compensation to the lack of accuracy of the analog thumb. But in Far Cry 4, even with the patch, the aim assistance is still broken. Please return to that existing efficient assistance in Far Cry 2 and 3, equal to the existing Borderlands ....'m avoiding playing Far Cry 4 for it. I play sitting on the couch and is very uncomfortable to use mouse / keyboard.
It seems that you improve a bit the enemy seek, aiming on hips, but that self-centering with iron sights really does not work !
I use official Xbox360 wirelles for windows.
