Twitchy isn't the word I would use to describe the new dungeon, first boss is a bit confusing (though that's probably the idea), second and third bosses are fine in my view. If anything I feel like it's slower than the previous ones it'd just like a little more clarity about the sizes of AoEs before their puddles are displayed.

I guess if you're reliant on the orange puddles then yeah, it's very twitchy but I think it's clear at this point that the orange puddles are not meant to be your AoE cues this expansion.
