It's strange. To me, it feels like they've gotten cheaper but not more difficult. I don't know when every dungeon boss mechanic started to give out vulnerability, but speaking as someone who goes in blind into all of them, seems they're all nearly "you got touched twice you die" even though they're not more complex or engaging.

I think so far ShB had better dungeon bosses/balance/mechanics with some exceptions. The first EW dungeon was fire though, really loved the hectic pace in that fight. I've just re-subbed so, might impression might change as I inevitably juggle my memory playing in the following days, but I remember having a similar thought in 6.0.
