[Classic] Good farming team?

[Apatheist]

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.

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

Dungeon farming will earn you more gold per hour than farming world mobs. You get a lot more drops, more silver per mob and a higher chance of getting lucky with BoE's blues/epics.

Adding a warlock gives you a lot of party utility from HP aura to curse of the elements that increases your mage DPS a lot. Hellfire and rain of fire synchronize well with arcane explosion and blizzard. Adding a warlock to a farming group will also give you the ability to recall your looter (by leaving your group while inside a dungeon so that you're automatically teleported back to your bind location. Ie. no hearthstone cooldown) sell junk and then summon yourself back.

Meeting stones outside dungeons in classic are just there to assist you finding group members. They can't summon players. Hearthstones have a 1 hour cooldown in classic and travelling is a huge timesink.
