GGG repair your Ultimatum pls

Hi!
Thank you to the developers for adding this mechanic to this league, but it doesn't work properly for me, I'll explain why (maybe it's just me, but I doubt it)
Scarabs don't work on maps at all, they work from time to time, at most scarabs don't add rounds to the other 10. This is just one point I found, there is another.
There are passives on atlas skils that add a chance at the end of the ultimatum to meet the boss (70 percent increased chance, skils: Brave The Tower, and 4 Ultimatum Boss Chance), 70 percent of how many? out of a million chances to meet him, to meet him I have to run 100+ maps.
Maybe there is someone here who plays, or played, and faced this, I understand that everyone plays on MF and farms millions of currency, but still, maybe there is a solution to this? Because i've been waiting for this mechanic for a long time!
