What they should do is make it such that everyone can only be hit by one special of that type every X amount of time. As in, you can only be hit by an AS once every 5 seconds, FA every 5 seconds etc etc for all the specials. That would kill off the multiboxers just insta-gibbing anyone with a team of 6 agents and what not, however it would hurt it in normal pvp where it ties into multi-person pvp.
However good show Michi.
