World of Warcraft does work under Wine alone, but I wouldn't recommend it. Rather, check out Codeweavers' Crossover Office. WoW installed and ran quite well under Dapper, though I can't speak for 6.10 as I've only had Mint for a few days and haven't gotten around to reinstalling the game. If you've already installed Wine, go ahead and update it before getting Crossover Office. The program isn't free, however. That said, I've found it to work with WoW better than Wine alone OR Transgaming's Cedega. Just my two bits.
