@unloveableone.
I find your post hard to believe. I’ve just come from roughly 5 hour session try to beat Mordremoth. A single segment of the final fight, up to “massive attack” took an average of 27 minutes to kite through.
3 successive attempts got me killed instantly and inescapably by the “massive attack.”
I see two possibilities;
A.) You are a god tier player and / or exceptionally lucky. Though if that were the case, you’d be unlikely to put down others. Pros tend to be nice people.
B.) You aren’t being truthful.
L2P posts are seldom productive and you are wrong this time.
I was able to solo it on my reaper with a second try with no real bugs to be noticed so I don’t believe he’s lying.
