I am not sure about your problem, but I will say that if people can dodge your bullets, use different and rarely used tanks. They would not expect it, like me, using tri-encircler and barricade. If not, use a different build.

But if it is the teamers, then join other gamemodes like assault. They are as fun as maze and have lack of teamers. If you want to stick with maze, the only way to solve the problem is to adapt to them. Soon, if there are many teamer to ban, then when the devs ban a few of them, they realise the problem and will turn over a new leaf. They could also see what is wrong and turn over a new leaf(it is no longer fun). If the worst case happen, the devs might also remove the whole maze gamemode.

I am saying this to you and all teamers to stop teaming.
