Our 10ppl is having a problem with dps, boss goes into enrage on less then 5%.
Main issue is this.
Ranged dps should kick the f off tha legs and mainly focus on boss? Or they should help on them?
It's basically a hard 520k raid dps check, so the answer is "whichever nets your particular raid comp more dps". I've seen people swear by both approaches.
Multi-dotting some or all of the legs could help, or leaving them entirely to the melee & focusing the body could help, or a little bit of both depending on whether range is in a position to get the damage bonus could help.
Consider leaving the least accessible leg up and/or having range take it out. Melee taking out whichever front leg is in the pheromone trail can waste too much time frigging around dodging swipe/trail & make it more advantageous to ignore it so that the mended leg is always one of the more accessibly positioned.
If you've got a plate tank & haven't done it already, you can probably net a significant amount more damage by having them swap to a pure dps set+spec. Plate armor and a bit of stam gear means that even a ret paladin can soak swipes. Unfortunately not so true for a druid out of bear form & I'm not familiar with monks.
