Hello everyone,
I am thinking about returning to WoW and firing up a 5 box team. I have been doing some reading here about group compositions and it seems a bit overwhelming. I have done extensive boxing in Everquest, so ISBoxer setups don't scare me. What group composition do people recommend? Since it takes awhile to level and gear, I want to try and get the choice correct at the start.

Things to note:
1) I have no interest in boxing in PvP. Any PvP I will do will be solo queued.
2) I mainly want to do dungeons and doubtful I will also have time to raid in a guild.
3) In the past, I have played many different classes and can't say that there are any that I do not like.
4) I am open to any combinations.

I have seen that there are some people who like 5 x one class and others that run 4 x and 1 healer and others who run 1 tank, 3dps, and 1 healer. Any recommendations on what to start with for the long haul?

Thanks!
