I actually like the design of a fight that kind of lets you go quite far even if you mess things up, only to meet a hard enrage because of a tighter DPS check. Also I like fights with no downtimes (compared to that horrible O10S)
I guess now the gear has helped a bit, but those pesky flying mobs are quite a good idea in my opinion. It was surprising for a second turn to ask for an execution that tight, especially in the first weeks, but I enjoyed it a lot.
