resto druid + 4 dk?

Currently have an 80 druid as my only horde character and was considering faction changing him to be with the rest of my guys but then thought about running him as resto with 4 dk's after reading about the success everyone has been having with melee groups now.

I was originally considering running 5 druids but I guess the lazy part of me sees that I could start with the DK's and get straight to outland instance boosting rather than going from level 1.

Am figuring that I run the druid resto, one DK as tank and the other 3 as dps and was wondering if anyone has tried this yet (or a similar setup such as holy pally, 3 ret, 1 prot, etc) and if it has been as successful as running tank + 4 ret pals. I'm just concerned that the main reason for the pal success is the fol spam from aow procs and having only one healer could be a limitation....then again, run all the dps DK's as blood with worms and healing should be a bit easier still.

Anyway, advice and opinions gratefully accepted :)

Its nice but the mitigation with the dks is alot trust me. I try resto druid 4 dks in pvp and its tidious getting everyone to stack. If your gonna do dks and resto druid do horde tauren. They have a larger hit box so they dont need to be stacked on each other. Dk tanks are mitigation intensive themselves even more so then the dps side. But i cant throw ne one off what they want to try. Go ahead and try it yourself use ur druid as healing even in ramps so u can get an idea how to work them and see how u like it.
