I guess I could see it being possible if one MRD tanked batraal while the other handled all the adds with a mage? Is a MRD handling multiple skeletons possible?

1 MRD on Batraal with 1 healer. Everyone else clumps up skeletons and banish/scourge/wide volley ect them down takes about 15~20 seconds at most.
