I'm wearing roughly 1/2 epics (Crafted, Valor, Raid, Tier) and 1/2 Heroic blues. I'm stacking INT, Hit-Cap, Then Haste/Crit about roughly equal. I have no "healer" (read spirit gear) and I have no PVP gear - so no "Wasted" itemization.
My rotation is Orb, scorch (For debuff), LB , FB until procs for Pyro! - If the debuff is up I spam FB until procs always trying to replace LB after it clears. On the start of some fights, I will force cast Pyro in the hope of hitting a large crit, getting the Ignite, dropping on a LB.
IF I get a big crit early and my Combustion Helper shows an indicated Combustion of 10k+ I will Combust. If it does not get a big crit, I feel like haveing the scorch/pyro dubuff up is a decent way to at least start things.
I've noticed on several fights that I have not been able to get a big enough crit to reasonably use combustion. (If your indicated combustion is like 5-6k, that's not going to really be a great use of a 2m CD.) However, there comes a point of diminishing returns.... If you wait all fight to get off one huge Combust at 20k (indicated) but you wasted 6-7 minutes to do it - you have missed 3 combustions....
Is anyone else frustrated with the RNG?
