On this fight I can fisweave, will be very nice for eminence heals and DPS w/ chi explosion to help heal the dog people, but we can also bring in the shammy for this one cause spirit link totem may be even better, and I can use the echoes talent so it's up for every dog phase. IDK about her firestorm on myth, but if it's only like 50% more than her one on heroic, then one tranq is enough per, so if I had the shammy for this fight, we can have me pop spirit link and tide for one, and link and ascendance for the second one.
She has a long enrage so 6 heals is pretty legit if we can manage to kill the doggies in time, and since we can stack em, that might be a viable option.
Another option is having one of our other shammies go resto and I go on monk so I can fistweave, and we'd have an extra melee in the stack grp to absorb the dmg from spirit link.
Also I can be in ranged as a monk so I can take a molten torrent w/ diffuse when dogs arent out.
