The original idea is also (no offense) not very solid flavor-wise, because the gun SHOULD restrict my view while I'm sitting in it, otherwise nobody would ever get out of them.
For heavy guns, but for light guns I'm just pointing a turret. No reason I couldn't look left.
I wouldn't mind this being a key you can press.
Yeah, but light guns don't obscure your view that much in the first place.
Andika, your situation is a corner case. The lochnagar troll (christ I hate that ammo, it should only be given to gunners level 6 and above because the potential for malice or stupidity is too high otherwise) ruined your game for 1 match, after which you reported him and he got banned. Problem solved. As for captains who don't talk to you, that's simply because they're not very good captains who don't know that this is a game about teamwork and coordination between crew, not just everyone quietly doing their own thing.
As for the pilot being able to rotate their head 360 degrees, yeah I consider a bug. In an ideal world there'd be a 90-degree arc facing opposite the helm which you couldn't look into without letting go of the wheel. I'll add that to my list of feature requests.
TL;DR I am suspicious/opposed to any change that makes crew members independent of one another, because depending on each other is what GOI is all about.
