A part of me is temporarily cool with it because everything is so predictable, but then there's the simple fact that this game was clearly built with the mindset of reacting to and evading attacks on the fly. I'd likely be in a bit of trouble if I couldn't preemptively move from attacks that I knew were coming in the next second or so, and it is primarily because this game is so wonky with hitboxes and client/server synchronicity.
But in theory, I'd love encounters with tough bosses that had no single set in stone rotation. I just very much doubt this game will ever be able to accomplish that in a satisfying manner.
