1st person Tank and IFV sensitivity.

After the recent season 2 update, I have noticed that my 1st person sensitivity for the Tank/IFV has changed to such a degree that I simply cannot play these vehicles anymore.

I physically don't have enough mouse mat to even make a 5 degree rotation with the turret whilst my 3rd person perspective is working as normal.

I feel as if the 1st person perspective has been fixed rigidly and directly to the turn speed of the turret, whereas before it felt as if I could turn the camera as fast as I needed and had to wait for the turret to come to position like it is in 3rd person (which I much, much, much preferred). 

Something is definitely wrong with the 1st person perspective sensitivity as again, I literally cannot play in 1st person whatsoever without my working man's hands literally cramping up and smashing my mouse into the wall just to make even remotely small rotation of the turret.

Please, please, PLEASE, revert the changes made, as it has single handedly ruined vehicle combat for me and I'm sure many others.
