I see you, you said in your gear. So, no 4pc. Didn't see that before, my bad.
This sounds like a difference in terms of what we mean by skill cap. To me, the skill of moonkin has always been around maximizing hardcasts. Pressing a specific, simple sequence over and over and agin (1x SS, 1x LS, 1xSS, 2xSW) is not a difficult thing to do. It's even a relatively mobile sequence since 40% of it consists of instant cast spells. Maximizing IFE by requires navigating the encounter and mechanics and movement well which also is where the vast vast majority of skillcap exists for either spec.The ED skill cap is literally miles above IFE. I'm not sure how you could ever argue otherwise. IFE literally doesn't make the rotation any harder, it does increase the difference between the good and the bad player a bit because of the double dipping, but nowhere near the swing you see with ED.
[/quote]No you can't. It is dead on aoe, and it is middle of the pack in most multi target scenarios.
IFE however? Now THAT one you can pretty much always use. Best for all kinds of aoe (unless you only care about a <2 min. window, but that is rarely ever the case in pve). Nearly as good as the best single target option for the elite, and actual #1 single target for the vast majority of the playerbase.
In specific aoe situations? no, you cant use it. But there's always plenty of opportunity to get most out of it in the rest of the encounter. In any case, I had in mind single target situations like the ones you simmed. I don't dispute that IFE is better for total dps in non-single target situations. But then again, moonkin is going to be bad in those situations IFE or not. It's just less bad.
The scaling from mastery is not trivial. I currently have 5500 mastery. The buff to scaling means my starsurge hits 4% harder. If i get 35% of my damage from SS, the scaling is a 1.6% total buff. That's what ED moonkin get going by guarm logs. If i get 22% of my damage from SS (non ED moonkin on guarm), I get only a 0.88% total buff. When we're making claims about a few % obviously that stuff matters. Add in 4pc 20% buff to SS multiplied through that? Significant stuff that starts adding up.
