I need suggestions on what to do.

Should i keep playing my level 77 Alliance Paladins(4 of them), Or should i move into my Quad DK group?

As of right now my Paladins are managing in dungeons, But with lack of DPS, Ret doesn't seem to be as "effective" as Prot spec, as strange as that sounds. Even though i'm pushing 1200-1300 DPS as Prot, boss fights still take a few, but are really easy, I've even 'carried' a few healers through instances because they don't need to throw heals as often with a directed macro on the 3 slaves to lead for WoG heals.

But all in all, I'm really not sure which to play, I just would like some overall suggestions / tips / pointers, etc. I am honestly thinking of playing the 4 DK's and running my 5th account as a healer (4DK 1 Holy Paladin), as the Paladin is level 64, equal level of the Death Knight group.

All tips, suggestions, feedback, etc, is appreciated..

Thanks.
