NCSoft has been somewhat vague from start wrt to multiboxing. At this point in time I don't think I would risk multiboxing if I wanted to play long term.

Not to mention that it seems like every Aion player wants to lynch all the botters. What? You're not a botter? Well good luck convincing the ignorant masses you're not botting.

Whether NCSoft actually cares about botting remains to be seen, but if they somehow change their tune I have a feeling that multiboxing will be the victim of collateral damage from any anti-botting movement made by them.
