Classic Sadana Bloodfury in SBG bugged?

Was wondering if the first in SBG is bugged? Was attempting a +19 and had her gaining the damage increase buff (Dark Communion) without any adds reaching her, three times. There was one mob that was uncomfortably clos, but the evoker in our group knocked it away.Am I missing something here, or is that just a bug? via /r/wow https://ift.tt/ML9HSfF
