A4 is indeed a very hard healer check but honestly I love it. A1-3 are all DPS checks and as a healer I get so tired of getting stuck with bad DPS and feeling like I can't do anything more than pop into cleric stance as much as I can and sometimes even that's not enough to beat the enrage timer lol. I honestly prefer A4 to A3. So many enrages because of comically slow DPS.

Honestly HW in general seems to be heavier on DPS checks. I was glad to finally see a fight where you really got tested on your healers.
