Rizla and Scott, I bet you would be pissed of if you get in server at 3:00 a.m. GMT timezone, and find that a guy named Chariot just enter server to get tank, and with his ping being 350, it's almost impossible to kill the tank, and he only remains near the spray and paint area... so my opinion would be, remove the possibility to repair tank, or remove the tank...
Scott says the tank is one of the main features of the server, but I think that your opinion is OUTDATED, due to server lacking players, and a random player abusing tank respray.
Cheers.
