I have several char- zerker, warden, wizard. They each do equally well alone. The zerker always runs low on health, ditto for the warden, but they can heal. Interestingly I haven't had problems w/ my wizzy, but that remains to be seen(Still leveling)
Bottom line: pick a class that interests you. I joined WoW with a friend and couldnt get intersted until I found a Troll Mage. Give your Char. a story, and 'role-play' (not like the wierdos), but keep it interesting. Enjoy
