I currently am gemmed/reforged to mastery (from ToT) and I grabbed Selfless Healer instead of Eternal Flame (I figure with the nerf it really wasn't quite worth it). I have noticed that my mana has been AMAZING - I barely dip below 50% and I am ALWAYS casting something!
I am now confused because I see people still saying EF is good (which I'm unsure of, I mean our PROT paladin that we raid with has 85k EF TICKS - so it makes me feel like ours is just mediocre). But lately I've also seen a lot of people say they're going haste now instead of mastery.
I know crit is still our worst stat, but can people explain to me why haste>mastery? or why are you going mastery>haste still? I am unsure of what's right for me.
