Today I managed to get:

* 3 chest in BRH + 2, with Shaman heals
* 3 chest in Maw +4, with Druid heals.
* 2 chest in Nelth +7, with Druid heals.
* 0 chest (but finished) in HoV +7, with Pally heals. 1 shot all bosses, some of the trash pulls are rough though. Didn't occurred to me until later that I should be using binding shot.

I'm leaning towards Druid after today. I have a 2 and a 5 court of stars to try tomorrow and then maybe Karahzan before reset. HOTs are strong with Overflowing affix. Big pally heals = big overflowing absorbs.
