They took three steps forward with the tanks in RO2 and five back in my opinion. The improvement in damage modelling is superb and the interiors are sublime. But they trashed dedicated crew-teaming and removing the ability to enter/exit the vehicles makes them feel like a suit of weird armor, if that makes any sense.
Also changing gun control from WASD to mouse was a retograde step, the gunner should have WASD to control the turret, leaving the commander and driver to have WASD to direct the tank. The gunner shouldn't be able to direct the tank at all from his gun position, that is totally arcade. The ideal positions therefore, for a two-human crew, is one in the commander's cupola, directing the tank, and the other manning the gun. He could then switch between his gun and the driver's position.
Then there's the AI doing its own thing which absolutely sucks; it's a step too far due to it being counter-productive in a fight and also way too uber against targets.
There's always a chance TWI will change things, but highly unlikely.
