The other week, some friends scheduled a casuals/alts kara run, but the main healer couldn't make it for another hour. I REALLY wanted to go on my tankadin, so when things were looking like a "no go" I offered to dual box in my T5 equiv holy priest as off-heals while I MT'd on my Pally - the deal was that I would hold the healer's place with my priest, and at any point, folks could call it if they felt it wasn't working.

Well, the healer never showed, and We cleared all of Kara (except for Netherspite cuz it did run a little long) including the Chamber of Secrets boss without a serious problem.

I would never have attempted it except as a "it's either dual-box tank/heal or we have to call it for lack of heals", and with folks that I told up-front that I was dual boxing.

I agree 100% about only rolling for loot on one toon. In my case it wasn't an issue because my healers upgrades are all from Hyjal, BT, and Sunwell at this point, but on principal I would NEVER roll as if I were two people playing separate toons... I just consider it good manners (and good karma). Glad to see others feel that way too: it generates good will.

Nice work on Lurker... I find that fights that require movement coordination are often the hardest to dual box. I keep thinking of Blackheart the inciter and how the "time for fun" group MC causes me to get so spread out that I can never properly reaquire /follow before the next round. To manage to deal with Lurker, with that many toons, you have some MAD Skillz.
