I think this expansion I'm giving up on AST sadly. I agree with a lot of points made in this thread and yearn for the card system from Stormblood but it's never coming back and I'm okay with that.

♦ Button bloat is too much that in my 30 button setup I can't fit all the AST and Role skills. If Squeenix is pushing that the seals dont matter and I should always be using them then a) get rid of undraw b) combine draw/play and Minor Arcana/Crown Play. I have sadly removed Synastry from my hotbar cause it never sees use and the moments that do are so rare that an AoE heal just seems the better option.
♦ Astrodyne. I like it but I don't love it. It keeps the class busy. It has required me to change my thought process of chasing 3 seals, 2 seems to be the goal now. If I play my cards right and Divination I can see a 17% Damage boost (selecting self for Play). I would like to see Astrodyne buffed in some way though as I don't feel that I'm missing out by ignoring it. An idea would be having Synastry apply the Astrodyne effect to its target too.
♦ I'm also not a fan of the Minor Arcana as it stands now. I prefered the SHB version because it was always used. No card felt like a waste. Now I hold onto the free AoE heal/Attack until I can draw the next one. I hated it in Stormblood and I hate it now but I also understand why it's back, because Seals dont matter and you should always use a card to get Astrodyne of sooner. If fishing for the right seal was more impactful then I would prefer us getting the ShB Minor arcana back.
♦ I miss Noct stance.
