Any other advice for the pally? Or any of our healers? Any info would be greatly appreciated.
Make better use of your mushrooms on rampages. Make sure you set them up on every rampage's stack point; When a rampage ends, you should be immediately setting them up on the next stack point. I can't recall what my shroom numbers were pre-buff, but since then they should absolutely be top 3. Yours was barely ahead of lifebloom.
Tell your shaman when to use Ancestral guidence. It's literally better than a tranquility in 10man. But, I run with a very high dps shaman so that may be different for you, since your shaman seems to be...very low on the dps (which in and of itself, may be the issue here; DPS; He was below both of your tanks on this fight = should not happen)
If poison bombs are causing big problems for you, you may want to consider swapping to Soul of the Forest. The poison bombs do a lot of AOE damage, however with SotF you can really top up much of the raid a lot faster on just about every single poison explosion. Run into a cluster of raid members; Cast Swiftmend on yourself so max targets get hit by Efflo, and WG = Winning.
The cinders just flat out suck. They're a mana drain for you, but they don't have to be. You should consider tracking your priests PW:S. And every time he/she does not PW:S the cinders target IMMEDIATELY, you should /slap your disc priest. All you should have to do is drop a rejuv on cinders target, with immediate PW:S from disc priest, and dispell the target the second YOU view it to be safely out of harms way.
