2, then 3 man group comp

Figured melee boxing would be extremely hard till i read up on it and played with some of the macros, and Interact with target...so im thinking now would be a good time to start my 3 boxing team...would be RAFing up two druids, or druid/rogue to 58 then bring in a DK to join them from 60-80..any comments..tried this before, think instances could be three manned with two resto druids + Dk?

Probably not at level, you'd probably have to out level them some to 3 box without any real DPS.
