A couple of counter points:

I definitely appreciate your angle on that, my feeling was it's a way to allow an off healing AST to get considerably more mileage out of cards than a main healer with the aim of the additional buffs and card tweaks elsewhere keeping things reasonably level by providing additional MP and an extra source of HPS if needed.

Regarding your points on 2&3. Ast have a respectable damage reduction via collective unconscious already and perhaps buffing this to 20% would have been a good suggestion for my list, personally I've never really seen or heard of bole getting use in Alex savage tho. As is it's just too erratic think of it as a consistent part of your kit. Depending on it to get through something like JKick would be horrifically sketchy at best. Also, I'm going to question your grasp of numbers if you think that a 150 potency regen for 30 seconds on a card is poor? That's an incredibly powerful card for both Sects and would be a highly worthwhile alternative to simply praying for Balance/Arrow. Having 300 potency of regen on tap would help Diu spend a few more GCDs on cards or dps, and of course it'll give Noct a source of steady HPS whilst they are sat in cleric. I really am sorry if you feel that spear is useful, have a scan over fflogs, it is by far the least used card.

On 4, again, please remember my stance is coming from an endgame perspective. Indomin is nothing short of incredible in the later Savage. An MP free instant 400 potency AoE heal every 30 seconds is like mana from heaven on Brute Justice <3

For 5, and as nice as gravity is, the numbers just don't add up for it, SCH will always pull far ahead on sustained aoe and WHM tends to be far more suited to big numbers on the opener thanks to PoM. The change to Lightspeed would help it's versatility and make them more appealing both for aoe burst in savage and also for 4 man roulettes.

I'm not sure why you feel that 7 is so bad? Benefic 1 would still also have the insta Bene2 proc. It's just an extra source of procs and again, it's something that would help an AST to push better numbers in both raids and roulettes. Why stance dance if you don't need to?

And yeah, agreed on the 5% cast time, I'd almost be inclined to suggest SE switched the sect bonuses around but that would be a slight Noct bubble nerf vs as Diu buff, not really what we want here =(
