2: The core kit buffs (particularly assize) are incredible. Thin air is an amazing ability and can save vast amounts of MP with careful use, if you're not finding a solid use for it then you're not trying hard enough frankly. Align it with PoM in dungeons to holy spam down a big pull. Use it in scruffy progression raids to get two free raises. Pocket it for big aoe phases to power through without using a drop of MP. It's arguably the best ability we got this expansion and it really redefines how aggressively a WHM can play this tier.

3: The 100% lily rate makes Divine Benison a very useful raid ability, it's also pretty potent in it's own right, a ~7.5k free instant cast bubble on a tank with a 30 second cooldown is nothing to be sniffed at when it's so easy to generate a lily now. I still feel that making it only cost one lily would be a positive change for casual content, but otherwise, it's a thumbs up from me and I need to keep pushing myself to use it more.

4: The jury is still out on the lily system itself imo. It has it's merits but currently you'll either generate more lilies than you can spend, or you'll barely generate any at all. If SE can smooth that out a bit, then it's golden. A 3 lily assize is a thing of beauty.

5: Solo questing? Drop protect, take cleric. What's the issue here?

6: meh, done to death elsewhere. The cooldown length bothers me a tad but the duration is better and we have so much HPS firepower that the potency gain nerf doesn't really notice tbh.

7: I defended 4.0 PI vigorously but even I had to admit that it was lacking in actual gameplay. It was just too inconsistent to be useful. I'm of the opinion that the ability is surprisingly tasty now, but the confession duration could perhaps do with upping a tad. Don't focus on the 3 stack values, rather think of it as a completely free 20%+ upfront boost to a medica II every minute that's completely independent of Largesse.

Regarding your closing points, I'm rather surprised by your views TBH. WHM is more fun than it's ever been imo, primarily because we have so much more MP to play with now.
