Please fix Gimmick/Unfair Bosses (Map bosses will be forced)

If bosses are gonna be made forced to spawn meaning to complete each map you have to kill that boss, there are a few bosses that just pull some really unfair shenanigans that need to be addressed, like one I just fought for instance Aurelian the Grand Adjudicator.

Damaging him no problem, I'm surviving dodging his hits and I'm about to kill him when all the sudden he becomes invulnerable... gets energy shield back loses all the debuffs I had inflicted and now I need to prepare for what? all of the sudden stone circle come out of the ground no indicator what I need to do see some openings in the circles and go make my way through to him, still cant damage him now hes slamming down pillars from the sky? ok I dodge, still can't damage him, does one more phase don't really know what happened but then he kills me, Ok fair enough I still have 2 tries

Repeat this again push him down to 1/8th of his hp and becomes invulnerable, energy shield is back and now ITS A DIFFERENT PHASE? I was prepared for the stone circles coming outta ground but now its a completley different phase throws me off guard and I start panic dodging, trying to finish him off but he's invulnerable??? what am I suppost to do theres no indicators nothing and now I have no revives left?

That doesn't feel fair or invigorating, not hard for the sake of being hard, that's not difficult that's just unfair... therws fair difficult, then theres unfair difficult, I find majority of the bosses to rely on gimmicks and mechanics I refer to as being unfair difficult, Bosses need set patterns, not rng phases like this, more indicators what to do like every boss 1 shots its just not fair

And now map bosses are gonna be mandatory to complete maps... some bosses are straight bugged even like The Black Crow, please fix these gimmick encounters and bug breaking boss fights.

+1

Bugged bosses need to be addressed as a priority. Black Crow is going to be so annoying to deal with if the fight keeps locking up with permanent invulnerability.

Now I hate this boss more. He is the only one I always die to. And now Digsite map is forced to have a map boss (him). It's a problem to me because I love to clear every single map around and never skip one. Now I'm level 98 and I died to him again lol. I really can't predict or react to his movesets. Plus if I have delirium or something on my screen I can't really see anything. I tried to search some complaint about this boss but there's none. Maybe it's my own skill issue. But god damn, I hate this boss so much.
