I played it for a while when it was still in beta. It was a fun game, but, at the time, I enjoyed wow more and didn't have time to play both. Stopped playing wow for good as I don't even have close to enough time. Can you buy tanks is WoTs now? Or are you basically limited with the t5 or t6 (I don't remember) purchased tanks with the rest requiring you to unlock the trees? If I can buy tanks/experience I might play it again, other wise it seems to take a LONG time to unlock stuff once you get up to t5 or 6.
I loved playing the arty tanks btw, so much fun raining death on the heavies.
