I have a Blood DK at 685 that's having trouble solo'ing heroic 5 mans. I was thinking of dual boxing a pocket healer, or maybe another blood DK to get me over the hump. With enough gear, I'm sure this stuff can be solo'd, but that process will take a while since I don't raid.

Assuming T.Jungle gear, what 2 classes can do 5 man heroic content the easiest? I'd consider 3 boxing at the most, if it would make things exceedingly easy. Don't care for pvp. Thanks.
