This is an incredibly badly designed list for the most part that would further destroy healers beyond the damage already done in SB and Shb

Good points in order of importance: scrapping dissipation, Swiftcast charges, readded spells, recombining draw/play

Everything else is absolutely awful
The removal of Selene devasted scholar, same thing that's happened with summoner, the pets becoming almost identical things that just float about is the exact opposite of a pet class. The two fairies offered flexible playstyle

Revival homogenisation and changes: NO we have had too much of it, otherwise crushnight basically says everything i wanted to

Light speed: this is a core Ast ability, by removing this, you are removing the only mp positive trait Ast has. Its also a functionally unique ability
Presence of mind: While WHM needs a nerf mp economy wise, scrapping this entirely is a bad idea as whm has several expensive mp abilities in short bursts
Synergy: Another unique Ast ability that helps it heal 2 tanks, or tank and the dumb dps who was too stupid to leave the aoe

Cure 3 revamp: it needs a slight mp cost nerf, but otherwise just saying it needs changes isnt enough so no.
Medica: tricky, there's a case for and against removing it
