Hey folks! So I just wrapped up my RAF leveling to 60 and now have a hard decision to make...what three characters (classes) do I level to 80? Here's my current list of available characters (and their current levels/specs):

Current Characters:
1. Warlock (61/Demon)
2. Mage (60/Frost)
3. Priest (60/Shadow)
4. Paladin (61/Prot)
5. Death Knight (61/Blood)
6. Shaman (61/Elemental)

I'm partial to the DK, since I had a blast leveling him up and so he's built into several of my team ideas.

Team Composition Ideas:
1. Death Knight, Paladin and Shaman (my "dream" team of sorts, but not sure how effective they will be)
2. Warlock, Mage and Priest (this was my RAF team, so I'm used to them)
3. Death Knight, Mage and Shaman

I should point out that my primary goal is to fill in some roles (healing and tanking) in the guild I'm currently in, so I'm keeping that in the back of my mind. However, I also want to enjoy the grind, since it's a long way to 80 (for me).

Finally, I have a good idea about specs for all of the characters BUT the DK. I plan on using the DK for my tanking (primarily because his gear is MUCH better than my Paladin). I was blood for the quest line, but am contemplating both unholy and frost. What I'm probably looking for is the the spec that requires the LEAST amount of babysitting for the DK?

Suggestions, thoughts, etc?

Thanks in advance!
