[Classic] Good farming team?

[pobdoq]

If you want to farm the place to do it is dungeons and raid trash. You get the best drop rates on everything, more stuff to DE and in some cases chances for some pretty nice BoE gear (ZG trash, Dire Maul.) One of the primary benefits of boxing is being able to farm content by yourself that is usually only accessible to groups. It doesn't make sense to farm locations that can be done solo as a boxer.

I was thinking of open world farming with an easy to use team, because I like brainless farming with music on or while watching series on a 2nd monitor after I get home from work. Though farming instances is also tempting, because it will probably result in more gold.

Something like:
druid, shaman, mage, mage, warlock.
paladin, priest, mage, mage, warlock.
etc.

Why not 3 mages? Don't they have the best aoe dmg in the game?
