With 2.45,
Tanks cannot reverse anymore, if there is a slight hill behind you, it becomes impossible to actually move. Truck's and APC's also suffer from this very problem and it sucks.
Spinning circles around a tank is not a tactic. Just because those 2 tanks (Puma and Greyhound) haven't been re-balanced doesn't mean that new players need to pay the price of more experienced individuals using a known imbalance to their advantage. (that means it is an exploit if it cannot be exercised by everyone in game)
It is a plain oversight of the tester's (among the many that exist) and needs to be addressed.
Using vehicles as they were designed to be employed is tactical but I don't recall reading histories of Puma's and greyhounds spinning circles around a tank in order to get enough shots off to effect a kill. The role of armoured reconnaisance is to identify the enemy, then get the hell out of dodge.
Not to spin circles and spit out infantry as the Squad leader dances away from the impossibly slow kill animation that the Anti-tankers have to contend with. Couple that problem with a new player in a tank and it gets very fucking annoying. (so much so, that the entire squad quit playing, instead of sticking through some more maps)
If this game is supposed to simulate reality, then let's maybe do so. If it's supposed to be Fh 1 arcade advanced then fine but enough of the crap about balance this, nerf that and pray that it all works out in the end.
