OCULUS: What the hell, Warmane?

What's up with that new mechanic that oneshots everyone when boss goes immune? Yes, I know we can move out of way but the smoothbrains that I get in RDF can't seem to figure that out even when I tell them multiple times before the boss fight and after we inevitably wipe. This used to be my fav dungeon to get from RDF HC because it gives a total of 7 EoT but now I hate it because we keep disbanding on last boss for 3 days.

Get rid of this mechanic, the players are too stupid to learn it and its ****ing us over!

It's working as intended.

HeroicPlanar Shift – Ley-Guardian Eregos shifts to the astral plane for 18 sec. While shifted, Eregos cannot move or attack but is immune to all damage. When Ley-Guardian Eregos shifts, he summons several Planar Anomalies that pursue players. ( https://www.wowhead.com/npc=27656/le...ounter-journal )
