It only took me like 5 attempts to figure out the mechanics and execute it with proper talents.
This is challenging ? Maybe depending on your skills. But for a mythic raider that is 8/10 this was done under an hour.
I think blizzard need to push the difficulty a little bit higher for the hard core raiders.
Mechanics :
- don't get hit by the melee add following you
- interrupt the add that spawn and cast an aoe that instant kill you
- go stand on a rune that is cast by the boss, if you dont stand in it an add will spawn with ~ 110m hp
- aoe down the adds
that is not alot of things going on....
