Alright, so I just finished the Main Storyline, fought the last boss...
I'll go over my thoughts on everything.
WHM on a whole is...well, i'm having mixed feelings. That is to say it's not Bad. again, i've said that.
The loss of stoneskin hurts still. especially with a lot of the massive raid wide damage going out. you need a Shielder and a full time Healer for the Primal fights. Yes, they have plenty of mechanics and one mess up can mean the end of the chance to not wipe. I'll impose greatly: a single death is really bad at this time. I've seen this from Susano'o to The final boss (spoilers, not saying :P ). I feel...bloody lacking at times. MP consumption is out the rear for these fights and even with Thin Air and Lucid Dreaming, and Assize...it never does seem like enough. This could be because of the raises that had to be done, which goes back to mechanic failures.
I want to address, more than anything: Planery Indulgence and Confession stacks. while it's a good AOE heal...i got...all of like...3 stacks total in the last boss, and that is with using Cure 1/2 like they're bloody water, popping every and all CDs to spend those lilies...
but...3 stacks, in an entire raid is Bad. yes, it's an emergency and nice heal, but...if you can't get the procs to use it, you're not getting anywhere. I used it to no end in the Level 70 MSQ dungeon. it came in handy, but that was a MUCH longer run with a lot more chances to get Confession stacks.
Solution: either up the rate in which confession stacks are given OR (and my personal thoughts on the matter) make them stack on the WHM, not the party to be a sudden snap AOE heal. Lilies and CDR...bleh, no. if SE is dead set on making WHM pump out heal numbers to high bloody heaven..then move the confession stacks and their mechanics.
