Let Scholar be the proactive healer. Continue to enhance it's shielding capabilities and give it more actions like Excog that let you preemptively deal with the problem. This to me lends to a tactical style of play that is quite enjoyable.

I think that Selene and Eos should still be pets that are available and different, but like SMN should be instant cast and also have Fairy Assault I etc. to limit hotbar consumption.

Let Scholars damage be based on DoTs. If it is necessary to lower their damage to be in line with the other healers, do so, but it was part of the classes identity and complexity that I think was lost with the suggested abilities so far

Keep Scholar as the preferred 'crit' archetype. This will give it synergy with DRG, MNK etc. and as you'll see as we continue, hopefully form not just 1 meta, but multiple viable compositions

Keep Astrologian as the wildcard (pun intended). Give Astrologian access to some shields and some regen but not as powerful as it's counter parts. Supplementary yes, but not to the point where it is better than both of the specialists in that field.

Let Astrologian cards have their randomness back. Most seem to dislike the change where cards have been all relegated to 'The Balance'. True many times people were fishing for that card specifically, but I would venture that that is an issue with the card itself, not the system in general. I think giving the Draw action charges was a great idea. However, in addition make it so that when a card is drawn, if Redraw (or it's equivalent) is selected then the previous card is not part of the pool that cards can be drawn from. Most of the frustration was about drawing spire after spire after spire. With this change that would no longer be an issue. Also, obviously make The Spire direct hit instead of TP.

Let Astrologians have Royal Road back, but not expanded. I can agree that giving those buffs to the entire party was a bit much, even with the reduced potency and made it difficult for 2 Astrologians to work well with each other. However, the flavor of strengthening or particularly extending the buffs felt very much like it lent to the fate and time aspects of Astrologians lore.

I believe that the addition of the seals is good fun and adds complexity as well. Bring back Time Dilation and other buffs that extend their buffs and I think the job is balanced.
