I main'ed WHM for all of ARR and I played WHM throughout the HW main story. It was my first level 60. I then transferred to the Astrologian after 3.2-ish. Here are my thoughts:

• The WHM just feels boring. They have a pre-set thing to do and that's it. I'm not saying its a boring class, it just feels like I always do the same things every dungeon and every raid.

• Being the designated MH is boring. Paired with an AST? MH. Paired with a SCH? MH. I like to do DPS too but they never pop out of cleric stance so I felt forced to always pop out early.

• There was no cool thing introduced in HW that the job got. Look at all the other jobs. Astrologian was introduced (also it sucked so bad at launch). Scholar got Broil, which is pretty good for their already good dps. Summoner got Dreadwyrm, BLM Enochian, BRD Wanderer's, DRG BotD. They all got stuff that radically changed the way it was played, whether through managing stacks, new skills, etc. WHM got.. some things. It felt lackluster.

Those are my thoughts. Agree or not, I've been a career WHM for all of ARR and the first several months of HW.

I like the idea of the WHM, the power-healer. The go-to job for healing your way through the heaviest of the damage. But FFXIV is not designed that way. The damage is always light with some 2+ seconds casted tankbusters. The game doesn't need a heavy healer in its current state.
