I would hate having Obliterate be part of the combat rotation (I dislike having to use a leap rotationally in fights since it causes positioning issues, one of the reasons I prefer combat over other specs)
My preference, now new abilities, after 7 months into 3.0 we are finally seeing a glimmer of balance which could all be wiped out in October if they decide to add new abilities to all specs and/or do major changes to discipline trees.
