I have been playing this game now for about three months. Here is what I think about the game:
Light tanks: Can take out any tanks in the game...include heavy tank (which should never happen). Most of the light tank have the speed to do thing (which the should) but still there is other tank just as fast or faster then the light tank.
Med. Tank is well balance. The problem here is light tanks can take them out with one hit
Heavy tank are ok. They have the armor but here again light tanks can do lots of damage to them and end up taking them out (and for a ww2 tank light tank can't do this).
Tank destroyers. These guys are so op. They have the speed, the damage, and the unbelievable long range killing damage. The only thing that isn't op for them is there armor.
Spg. These guys are way under. They are slow, damage not great (like there suppose to be), they so allot of under, over and to the side firing (even when crew is at 100%). Most spg are suppose to be the highest damage of any ww2 tanks. They have very slow loading time (slower then normal), most spg are open for the purpose of loading faster then other tanks (but not in this game).
Customer support is the worst I seen in any game. They don't answer your questions. Are they do is say get a video shot of it.
TO me this game is not worth spending any money on it, except to buy the tank destroyer as they are so op in this game.
