I'm not a 5 or 10 boxer like some here, but I can't see one person doing a 10 man dungeon by himself. Without going insane On some bosses where it's a tank & spank, it could work. But there are fights where there is a lot of movement/kiting/etc required by multiple characters at the same time. You would have to be seriously PRO to work that out. Not to mention how you would sort out and control the necessary multiple classes. I don't think 7 warlocks and 3 priests will cut it.

If you can 10 man Kara by yourself, I'll come out there and lick your balls all day long. :shock:
