I guess WoT is more like a MOBA than something like WOW. Two teams of 15 tanks each go at it for up to 15 minutes. As long as you don't do anything too stupid, you don't even have to talk to anyone, but you still get to benefit from everyone on the field being a real, thinking person. I can easily play for a couple hours, carry my weight on the team, and not even notice that it's multiplayer. Otherwise, it's a rather slow-paced shooter with generally realistic armor mechanics and a focus on strategy and positioning more than reflexes.
Being about tanks is also a pretty big plus, as far as I'm concerned.
