“One keystroke should only perform one action, on one character, on one account. Anything which is used to circumvent this would be a violation.”
A round robin system would play with this rule. Funny that the CS rep is too fucking stupid to understand how easy it is to abide by this rule and still multibox.

Round robin key

Keypress 1 Toon 1 attacks
Keypress 2 Toon 2 attacks
etc....

all pressing the same button.

What a tool.
