I could do with some advice from the experts and as they are busy I thougth I would ask you all 
My priest is about to hit 70 and currently SP spec I created her with the intention of healing for group stuff so am looking at re-spec
Could you suggest a good way on spending my talent points
Thanks
Surender/Faber
this would be my suggestion, having said that my experience with priests is limited

Nice spec except lightwell is pretty much useless because the healing from it breaks on damage so its better to pick up inner focus instead
