Class choices

To start, I only plan on dual-boxing.

I was wondering how a priest/warlock combo would work, or should I stick to the tried and true shammyslammy?

Thanks!

Edit: Can run 3 clients at once very well, so maybe a warlock warlock priest combo...or 3 shammyslammies

For 2's I can say that priest warlock is a decent combo. I went 23-19 in 2's on my s3-4 warlock/s2spriest. You have to play the LOS like a pro or you'll be taking a loss every time. You'll lose to almost every single rogue team that has half a brain, but other teams are fairly easy. Learn to stagger screams and howls separately, and burning people down from 50% during a silence to spell lock is key to most wins. Healer dps teams will be the easiest, except when it's healer + rogue. I play the spriest as the main window because he's much too squishy to leave as a clone. All warrior teams are easy enough to afk half the game. When you come across double dps, casters are secondary targets and who you put the felhunter on to keep them shut down while you kill the partner. Can't think of anything else atm, good luck. Oh yah, don't forget you have a decent drain team if need be. double healer teams will easily heal through your dots, but you can drain them so they aren't unbeatable. This goes for exceptionally well geared healers in the lower brackets who are able to keep their dps up through your dots as well. Drain them and it's game over for them.

I've tried Disc/SS as well, but that combo seems to require too much attention and micro management for each character making it near impossible to do well as a multiboxer in my opinion.

A warrior/priest combo worked really well for me for PVE content because the warrior was still fairly resilient even if she was DPSing. But definitely go for a caster if you're going to be doing PVP a lot!

priest warlock works well when the priest is shadow do to the added shadow damage. But like stated above and two chars that can stealth will be tough especially because your both clothies.

terrible combo
