So I'll keep this short, I really hate both aiming modes on blitz PC. With the auto aim mode, it's really hard to hit moving targets or see targets from far away since it always zooms in and out, but on the other hand, manual aim mode also messes my aiming up since I use shift to switch between the views which always messes my aiming up since I have to zoom in or out before even starting to aim.
Now to my suggestion; Semi_Automatic mode.
It's basically where the view zooms in like auto aim mode every time you aim at a tank, but you can freely control the zoom afterwards, and the zoom level resets every time you get out of sniper mode. It would just make life easier and I don't think is a complex feature thing to add.
Now I already know that this premise alone will trigger a lot of mobile players but please, I am tired of having to switch between these modes every few battles to then regret my decision and switch back.
