Xyxy.. try to keep your posts *outside* of the person you're quoting!

As for multi-boxing being exhausting multi-tasking? Please. It's still playing the same game. That's like saying a dps rogue in a 5-man is multi-tasking because he's got to focus on efficient dps, combo points, his energy bar, his threat meter and possibly dropping aggro, maybe some bandaging.. Or what about the 5-man healer who's got to focus on the tanks and everyone else's health while managing his own mana bar? *Every* good single-box player multi-tasks in this game already. Just because you're multi-boxing doesn't mean it's somehow more confusing to your brain after you get used to it.. it's still all within the same framework of structure of the game. What's more difficult for a brain to process - 5xShaman farming easy instances and all spec'd for chain lightning.. or a single warrior working on main tanking a raid?

Multi-boxing != multi-tasking any much more than single boxing != multi-tasking.
