We do what everyone here is say pretty much also. When I go w/ my warrior (DPS) I am the MA for the Skelies. We all gather on the MT, spread out when Rain of Bones starts hitting and single target burn them down. For myself once I see the Rain starting I will rush out pop bloodrage or imp zerker rage, tab target a skele, intercept back in and pop WW for inital agro from hits on the group. Pop DS, and cleave, WW as able to work them down.
Depending on the rest of the DPS make up we can have all the skeletons down w/ plenty of time for eveyone to get reset for when nightbane lands.
