I can understand your frustration, but by being patient you can use a few bosses in MA to wipe full teams. Such as miller and quade.
Sometimes if you are stuck with 2 afkers or leechers you gotta use what you can. I dont condone slidecasting or running down the clock, but soimetimes you can win by being patient, and win fairly. (heals +att spd buffs allow major headaches for opposition)
I'd rather gripe about those guillermes that run around witrh no intention of fighting hoping that they win the round by running down the clock.
