t-34 85 is like the spitfire of tanks. It is fast, its turret is fast, the HVAP rounds have a nice flat trajectory. I don't know if it is considered gamey but when I used tanks 87.3 percent of the time I would be shooting from the commander position and by sticking with one tank you basically would just get the hang of it without popping into the gunsight. I always found it harder to use the tanks with the super optics because my ranging would be way off. It seems important to be able to hit in one or 2 shots if the aggressor, one shot if on the defense, and be able to shoot on the move. It seems to me there are at least 3 different kinds of tank game in the game, the long range slugfest, the sneaky undersea warfare and the spawn mayhem furball. the t34 85 is a good all arounder. The spawn mayhem is a great place to work on your aim as the driving distance is usually short if not backwards, it might seem stupid but it really tunes up your aim and reactions, also it is a lesson in lag and its frustrations. The gunsight is important to shoot below trees and to make sure you are shooting over a berm instead of at it. The super optic tanks can see your tonsils while their tank is just a blurry speck so don't stand still if you are out ranged. The M4 76 is high profile but has a great rate of fire and the gunsight is bright and has good magnification and involves no dial turning.
I had very brief exposure to the old manual transmission version of GVing and I think, (someone will correct,) you had to shoot from the gunsight and you could have another player as a gunner. That was more fun as it was harder and scrambly where as cruising around plinking from the commander posititon with the asdw keys seems like just another video game. The thing is I suspect you put yourself at a severe disadvantage if you are a purist and get in the gun for every shot. Just my opinion.
