Yeah I read the patch notes, seems that it is only Normal, Veteran & Elite.
But in the same time, Zantai wrote
and Elite is not endgame afaik so he must mean that also Ultimate bosses deals more damage, that is how I interprent the qoute above.
Judging from another thread, I read that the the base game nemeses got some buffs, like Fabius and Iron maiden.
I can also tell that Bastion of Chaos in Ultimate is harder now than before. Before patch I could just cruise with a lesser-geared char. Now she can actually get hit pretty hard in there, also by champion mobs. I have done a substantial amount of runs so that I could tell that this was just not some bad luck with the mutators.
Let’s say this, I am a bit confused now
