I'm still learning the ropes of playing Tiger. It's not that strong at all and needs plenty of intel to be useful. Once that gun goes off though, so does it's target. Getting swamped by too many tanks is the problem I have.
Most fun I've yet had was in Pz III M, going around in SB and popping stuff up from side & behind. Really fun tank over all.
Only thing to complain about WT tanking so far; the bigger the tanks are, less fun it gets. As I'm storming the flag, I see teammates sitting in their better tanks almost at respawn, sending shells a kilometer away hoping to hit something vital. Yay. I always go for close up and personal, but that can mean I end up against 3-4 heavies and that's it then.
