I'm not sure either, I'm going to level my Rogue first together with my girlfriend, after that I think I'll go with ret pally + 2x elemenal shammy so I can do scenarios. Then I have to decide wether to go on with my disc prist + 4x DK or to level my lowbie 4x ret pallies.

At any rate, I'll and up with at least one pally, because I'd like to run 1x ret + 2x DK or 3x ret for scenarios, and probably 1x holy + 4x DK or 1x holy + 4x ret for BGs.
