I respec'd Arcane for a 10 man tonight to try it out again.
I do like the rotation a bit better than FFB and I like the fact that Arcane's DPS starts immediately and not after a ~20 seconds.
I have a couple questions though:
1.) What's the order of stats for Arcane? Hit > Spell Power > Haste > Crit ?
2.) I've read about a couple rotations. One being Arcane Blast x3, then casting Arcane Missiles whether Missile Barrage is proc'd or not and then clipping the 4th Missile with Arcane Barrage for the Buff. Second being Arcane Blast x3, then casting Arcane Barrage and only using Arcane Missiles when Missile Barrage is proc'd and also clipping the 4th Missile. IMO it seems like Arcane Missiles without MB proc'd would produce less DPS.
3.) I went oom like crazy on a couple of fights. I think using Mage Armor instead of Molten Armor would fix this, but how much of a DPS nerf is that? (I haven't tried this spec in a 25 man yet, so mana might not be an issue)
If anyone has any other comments, please post TY
