Michigan plays Ohio State this week in one of the most storied football rivalries of all time. This got me thinking about WoW rivalries. Sure, we only have two teams, the Horde and Alliance -- but we have tons of classes that hate each other, particularly on the forums.

Every class seems to have a rival or two. The rogues don't get along with the hunters, the paladins and priests are constantly fighting over healing, the warriors and druids argue about tanking, and none of the clothies like each other. Everyone seems to dislike a class that shares their role, whether it be DPS, healing or tanking.

But the current epic class rivalry is probably mage/warlock. The mages feel their spot as top caster DPS has been taken unfairly by the locks. The locks feel like everyone hates them and are causing their nerfs. Throw in that both classes compete for the same items and you've got quite a brouhaha.

What do you think is the best class rivalry in WoW?
