Well if you are duoing with a warrior, no matter how much you hate it, you will be doing some healing. Therefore enhancement/resto or elemental/resto is the way to go. Where the synergy comes in though is in totems, and I would favor an enhancement/resto build like 32 enhancement, 19 resto . That warrior is going to want improved strength of earth and improved wind fury totems, and you are going to wreck stuff fast like that. The only things I skip in the enhancement line are weapon mastery, toughness, anticipation, and shield spec. Since you are going to be laying down the totems, the resto side helps out alot with -25% mana on totems from totemic focus. You also pick up 70% uninterruptable healing with healing focus from resto which is important since you will be doing Mongo burst damage and will likely have rockbiter up, pulling aggro from the warrior and forcing you to heal while you are being beat upon. You also can get the nice natures guidance for improved hit.

My feel is that if you are shocking etc from elemental, you will not have mana for totems and healing which come first
