Here we go again

I for one didn't understand the first and the last boss of the dungeon. Died to the second, but at least learned something from it.
But that moment when the first boss went "now you no longer understand my mechanics" when I did not understand them anyway - hilarious

As hilarious as the "dungeons are hard, deal with it" crowd, which always needs to call others names instead of simply making their point. Makes you really wonder why it's always the unpleasant personalities that want harder content.

I for one didn't understand the first and the last boss of the dungeon.

First one drops a layout of two large and two small circles, along with a knockback aoe. A timer will tick down over one type or the other, then the other after it goes off. It also always alternates, so if knockback was first then next time it's the circles, and so on.
Once the crazy gas starts kicking in you get 2-3 seconds to look at the layout before all the circles go massive and the knockback doubles. The timer still goes over whatever's going to go off first, just strobing instead of counting down, so you can still plan out where you need to be.

Last boss you don't want to be hanging out with the memories of dead people how they died, that's how you die. First type is a cross beam over them, leading to the usual alternating crossed grid type attack. Second type is a circle aoe, massive on the crowds small on the loners, along with a standard "kills you if you're in it, but hug it to not fall to your death" knockback. Third type is two crowds running from a pair of sweeping beams.
