Hi,
We were clearing Rastakhan mythic (using the 4 doors at the entrance, then stacking ranged inside them to nuke Bwonsamdi to 50%) yesterday and during p3 in the death realm we noticed Bwonsamdi started to cast inevitable's end 20secs into the phase. (~70%)
our first kill of this boss he did not cast it and during progression he didnt cast it for a while in the death realm. (when he was close to 50%)
this happened multiple times. - I have checked a bunch of logs from last night and see guilds with less dps not seeing it being cast?
we ended up killing him but were surprised that blizzard would hot fix something 7 weeks after release. hopefully we got unlucky.
edit: clearer post
