On a side note : most classes have hand grenades that can kill the tank very easily as they explode on contact.
The only real issue here is the fact that Kalphiter keeps saying "dededededed" all the time like an starfish. He solo'd tanks before and even edited the stats of them when he had Super Admin on the server. I'm not sure if I can do much more against tank abuse but I added a "Don't be a richard to other players" rule.
However the tank itself has reduced speed and both teams have a pair of them to use so I don't think it's a balancing problem.
Gravity Cat already thought about making a new tank which doesn't have a ridicolously overpowered main cannon but that might take a while.
It's the map's fault
The only problem of the map would be it's size.
Both bases have 3 exits and the land scape is filled with trees which hinder very fast movement with vehicles.
I will consider removing the tanks out of this TDM anyways.
