Honestly all REALLY wonderful changes. Senix looked at the problems with Astrologian in Endwalker and in previous expansions and decided to tackle all of them! So honestly, thank you for that. As someone who has mained every iteration of Ast ever, I really appreciate this direction.
That being said, I have only a few concerns. One of which is that card manipulation is now seemingly completely gone. Card manipulation has always been a fun part about astrologian. I think it's a big part of what many of us enjoyed about HW/SB astrologian. Just being able to cycle your cards, redraw your cards, change your cards into a buff for other cards, or change your cards into a lord/lady. Any type of card manipulation that we had is now gone. It was pretty much dead in endwalker with redraw being our only option, but I still think it will be missed and I hope it returns in a future expansion in some way.
My only other concern, with the information we have so far, is that our cards might be a little bit too generic. One dps buff, one heal (hot or instant), one mitigation (damage reduction). Those are all great, but they don't have any flavor to them. So what I mean is that in any game, a buff that shoots missiles or debuffs targets that you attack while the buff is active will always be more fun than a button that just does +x% damage. -x% damage taken. If the new offensive card, and new mitigation card are too simple in such a way, then I think we should consider spicing them up for 8.x
