SK - Dire Strangulation is an assigned debuff to cast on the mob. sorry necros...
Bond of Bonemaw is a heal - unfortunately it does take up the debuff slot, but it is used while ramp tanking to continue getting healing while invuln/lessen healer load. can be cast on multiple mobs - 10s recast, tons of good healing btw. doesn't do huge damage, but i wouldn't cut this out of a lineup.
Harm Touch - comes with the dot tagging along. its a 20m reuse so shouldn't be considered much beyond its single use per SK.
all told - 37 casts of bond of bonemaw.
15 casts of dire strangulation
1 cast of harm touch
the fight also does not break down the dps from the add mob ritualists and the main mobs.
Raccoo's 8 casts of the 2 dots isn't a heavy load to be fair. - and while fleeting is up, shaman can and should have a little fun. at the very least on the adds.
IMO - languid bite should not be used if avoidable and disabled, the dot is not worth it. shaman have nowhere near the crit modifications that necros have. so while the base damage on your spell is nice, it will not crit nearly as high as a necro spell with half the base damage.
