I just took the plunge into multi boxing and registered 5 accounts. On my main account I have a:

100 prot pally
100 rogue
100 warlock
100 hunter

I'm just looking to do some heroic mode dungeons, TW dungeons, and Tanaan. What would be the easiest combo for a first timer to accomplish this? My Warlock has a the legendary ring so I'd like to use it at the least.

Thanks in advance!
