To be fair, my perception is that the bosses in dungeons has been consistently good, and even slightly better with DT. The Trials have been knockout (apart from the last). The first normals were knockout. (With the exclusion of Deadwalk boss 1 wich was awful. Brave, new, but awful).
The problem with dungeons is that everything between bosses has got worse, *and that really matters*.They have even en-shitified previously good dungeons in their push to cater for solo players while avoiding having to do any dev for it.
And it WILL bec stimying dungeons, badly. Every design will be "is this going to be hard to turn into solo?"
'They can have anything they want in dungeons as long as we don't need to develop new AI for it. i.e., nothing very new at all.'
My god, could you imagine the outrage if they started enshitifying ultimates to make them easy to convert to solo instances. The content creators would be issuing progroms and declaring holy wars. Organised via discord no doubt.
Of course still nothing compared to the effort that goes into savage. They could put that much richness into normals while lessening the brutality (adds, phase changes). They just can't be bothered is all.
