Dear SE/Yoshida/Whichever rep bothers to read this.
You quite literally have no idea what you are doing with healers, or how they are played at a high level.
This was painfully evident with 4.0 and it's looking like 5.0 is going to be repeat of the same.
I cannot stress the following enough:
You desperately need to expand the job design team with a couple of individuals who have some enthusiasm, motivation and high level experience with the healer role.
The changes shown in the media build are simply not good enough.
Some quick notes and observations:
WHM's 5.0 upgrade consists of the things it should have gotten with 4.0. The PI change makes me think that SE still don't understand WHM's clipping woes and Misery isn't going to line up nicely. It's a good job SE saw fit to give them some party utility.... oh wait. They do have an advantage in raw dps potency across the board now, but I'm not particularly hopeful that it'll outweigh AST's cast time advantages.
As for SCH? I wonder how many SCHs at the very highest end of play are looking at these changes in disbelief. Critlo on a button is going to be interesting. Seraph looks pretty solid and I'm quietly hoping that fairy potency will work of your own stats thus scaling a little better. But that's literally all I've got. Outside of that, the job's skill ceiling just crashed hard. Fairy micromanagement is gone as is their DPS play. Enjoy your new expansion peoples, be grateful SE at least remembered to give you a spammable AoE this time round.
AST did relatively alright with CU being the most significant nerf that I can see. The new cards will offer a little less burst in exchange for a lot more consistency but at the expense of being able to use cards and CDs for MP. It's important to note that this could be an issue on par with WHM's MP starvation circa 3.4 or it could be a non issue. Redraw, Sleeve Draw and Minor Arcana are massive improvements and whilst personally I'm not a fan of the new draw/play mechanic, it'll be a positive change once hotkeys are jiggled a little bit. It's also noteworthy that AST still retain their cast time advantage with Malefic.
Tentative thumbs up for AST. WHM is still stuck firmly in the past. SCH's are getting flashbacks of 4.0.
