Looking at the blood legion video, it seems they prioritise the highest damaging slimes ahead of purple. Does this work in 10 man? If so, are there any combinations where purple must be killed at all costs?
I gather yellow is the highest priority, as the raid wide damage is just silly, especially with a red. But what others come highly prioritised? If it was red/blue/green/yellow, then what would be killed?
Finally, how do healers go about healing aoe damage with purple? Is it just a case of only using direct heals, and giving healers certain player assignments to enable easier control over stacks? We run with a disc priest, holy paladin and resto druid (or 2x resto druid and 1x holy paladin). Any recommendations on how to survive particular colours if we leave up purple?
Generally we run with:
Prot pally
holy pally
resto druid
disc priest
moonkin
mm hunter
rogue
arms warrior
frost dk
arcane/fire mage
