since 8.0, the first boss in hellfire citadell is basically broken not soloable. google research showed, that blizzard was made aware of this issue at the blizzcon.
i remember blizzard fixing soloing SoO in 7.1 so i kinda hope for the fix of HfC in 8.1
does anybody know or can test if something was changed? i cant find anything at the patchnotes.
