Returning Boxer... Looking for Group advice

[Wubsie]

The hard thing about composition question is that unless someone happens to be running the exact same comp, it's very hard to estimate the viability.

That being said, I honestly don't think any of those compositions would be too problematic. BM Hunter should be basically as reliable as you'll find with ranged DPS. Pally and DK are the current top tanks so there the question is mainly one of preferene on the utility and feel of the spec. For healers I think both Pally and Shaman should do fine. They have fairly strong cooldowns, some nice utility and should not be at all hard set up for a pro-configuration.

Personally I'm a big believer in playing the classes and specs you like over what might be the "best" composition for my overall enjoyment of the game. Not sure that applies to everyone, but I think it's a worthwhile consideration.
