It saddens me to say that Dawntrail Astro is weird and very messy. I think it's a step in the right direction conceptually but it's so chaotic, even in casual content.

Here are my thoughts on how to change it.

Change all/most of the standard spells to be the cards, have no randomness and just have the spell names be the cards. An example would be, change "Aspected Benefic" to "Ewer" or something. This is so the job can have it's fortune teller identity but not be over complicated. I don't think the devs would do this but they have tried to cram two massive identities into one job, the Time Mage and the Fortune Teller. This change would focus the idea into just FT rather than TM.

My second idea, one they would actually do. Very simply make the card draws every two minuets and buff the cards.

Currently I imagine they were thinking you'd expend all your cards before the next draw, but there's a massive possibility you don't even need to use some or all of the support cards you get, which means you can end up wasting cards which feels stupid. If you just throw them out there even if not needed then you end up having to weave useless buffs in-between attacking. Which just feels insane. And if "Draw" gets out of time with the two mins (very easy to do) then getting DPS cards in the buff window can be out of the question. If it was every two mins rather than one this would get rid of a lot of stress and you'll have a lot more time to use all the support cards.
