10 days later and, besides not having much time, i just couldn't help myself, watching to my left side and see the pc off. I had to start again, and this time with only 4 shamans (only!). Because it works better, not having to bother with that extra shaman that stays behing in rating, switch between arenas, and finally i can party with a friend and go av.
I dunno, i just couldn't let all this work go to waste. Multiboxing is much more than sync'd attacks. It's a game inside the game.
