3 boxing - What classes?

Hey guys, im new multiboxing and can only afford three right now.
What classes do you recommend?

Priest or mage or rogue or druid or shaman or warlock or hunter or paladin or warrior. To give you a more effective answer we'd need a tad more information. What are your goals? Dreams aspiration's etc :)

wow, that was quick, im just looking to play around and get the feel for it.
Was wondering if you guys recommend having a healer or all dps

I stated with 3 warlocks but have been playing with the idea of two warlocks and a healer

Healer/dps isn't too bad, it gets a little more complicated when you get into healer/tank/dps :P I'm sure you'd do fine with a healer/2 locks. My suggestion for the healer? Shaman :D

First chain heal is op second I'm drawing a blank on the name atm but it makes you cast faster HEROISM thats the one. Heroismd SoC's pewpewpew :D

I'd have to say two warlocks and a shadow priest. I think you'd have a little better synergy going on with that combo and all the shadow damage.

Another option would be two shaman and a paladin. The nice thing about this combo is you would have a lot of options on how you can spec to create really any combo of dps/healers/tank you want. From there it'd also be very easy to move up to a 5 man team.
