that tetherball is a brilliant idea
It's a total exploit of the AI's need to constantly shoot enemies.
The brillant part is that as the mine is shot, the momentum is greatly increased (and this is important with mines, faster it goes the harder it hits). So this creates a fast moving 1 hit kill machine that dominates people. Especially since the angle of the shooting affects the direction the mine will come in at.
They get raped because they did it to themselves, and it's loving hilarious.
