I would (and I am) stay with your best DPS/Grinding build. Then come lvl 70 re-spec back to a more usefull roll. As a warrior I am specign to MS Two Handed for the grind. This build has worked well for me in the past, it is what I know. At 70 I will be specing back to a full Prot Tank and be more usefull to the group.
