i stopped using the GV's altogether after the asdw thing came out. but now that they re-enabled using the rudder and joystick again, for me its been a great addition. we were using the tanks the other night and it was alot of fun. the new aspects of the controls bring a fun change to the game.
i like what they have done, and will try to utilize it by having some sort of tank battle in the near future in the AVA!
