Patience is one of the big virtues in tanking,
upping into a camped spawn isn't always the way to go either, but if you must
, use the t-34s, the turret traverses faster than most, it will also take a little more punishment than the panzer.
To break a spawn camp it always helps to up in large numbers together .
If you'd like too, I can meet up with you and we can go over some of the finer points of GVs in AH2, just let me know.
P.S. Tanking can bring you a more instant gratification in ability to get into a fight right now!! It can also get you back into the tower much faster, learning the spawns and driving a ways to the fight isn't always a bad thing!
