There's nothing evil about Possession. (Well, I mean, it's totally evil, but I mean nobody is going to mock you in /global, especially for just bonking around Khitai.)
Did I miss the reason why you're not just going full Possession and taking Chains of Anguish again?
5/5 Flame Lash isn't really necessary unless you're taking Inferno. Inferno is good for solo PVE, although it shines best when you're really mass-pulling.
Burning Words actually stings pretty good. It's good for when a mass pull goes bad and you've got to bail with the mobs still with a decent amount of health; root them, run out of range to let pots tick, then regroup with the scales back in your favor.
