On the note of Lord, Lady and Astrodyne I see them as an improvement on the current kit.
This is because the current card mechanics are:
Draw -> Get The Balance with one symbol -> Play
Draw -> Get The Balance with the same symbol -> Redraw -> Get The Balance with another symbol -> Play
Draw -> Get The Balance with one of the above symbols -> Redraw -> Same Again -> Redraw -> Same Again -> Turn it into a slightly better version of The Balance with no symbol
Draw -> Get The Balance with the symbol I want -> Play
Use an AoE version of The Balance
Naturally the people who liked having variety in what cards complained about this drastic change to the card system where every card is now The Balance.
These changes alleviate that problem.
With the Minor Arcana changes, I think they could be better, but I at least don't have to immediately play that healing card and it's another DPS spell I could use in my downtime, even if it's a 50% chance, but hey, DNC get a 50% chance of getting a Fan Dance. But most that's 2 fewer chards that are "The Balance"
With Astrodyne. It's not just a DPS buff, if this mechanic was still used for Divination THEN it would just be a DPS buff. Fortunately Divination is it own thing now. I think biggest benefit I see is the cast time and recast time reductions - it could knock 12 seconds off of a Macrocosmos recast and can get in most DPS and heal moves in within a shorter space of time. There's also an MP regen benefit (though it's niche, but you're still gonna find it useful if you're raising or are in a challenging group) and also a healing boost from it.
So it's a more meaningful benefit that "I will use 3 The Balance cards to determine how much of The Balance I can get from this AoE version of The Balance". I don't mind 6.0 Divination going to a flat percentage to get something more meaningful for the Card system.
I feel like the changes to Draw/Redraw might actually feel better. Because it never feels good to me to do multiple redraws to get the card you want, it messes with my flow, but the bit that is nonsensical for me is why Sleeve Draw is gone, in 5.0 it was clunky as heck, sure, but how they fixed it I think would have be beneficial to the 6.0 kit and reduce some of the RNG fatigue.
