Sorry to name drop here, but I was taking a look at Owlds' spec from EU Xavius <Method> and he is using an 8/2/31 spec. I've never seen this before, usually I see people losing a talent in Genesis and the points in furor to hit Moonglow.
To be honest though, his spec makes so much sense surely, because although your heals will cost 3% more, you will have 10% more mana. I'm taking his spec for now because I really cant find a flaw with it, but I wanted your opinions because I'm interested in what you think.
here is the spec: http://eu.battle.net/wow/en/tool/tal...QaQd!WVUgTOmpu
