Personally, i feel that adding a cool down on balance fishing is all that changed from stormblood till now.

If i have to think on my feet to get three seals while weaving, dodging, and healing, then let me play them when i have my set of 3.

I understand with AST's current Kit and Potencies that this would break the meta. So lets think about how this could be doable!

EX: I know that sleeve draw would probably make completing divination too easy and frequently occuring. Maybe Sleeve draw could be changed to an ability that just completes the set of seals when you have 2 already.

That would fix a lot of the unnecessary business of the job. Spamming redraw isn't fun, and if you are left with three draws, and three redraws completing divination is taxing while almost assured.

Furthermore you should just start combat with 3 seals and no card.

These are obviously just my ideas so far and i know the community as a whole are more clever and innovative than i am. I can imagine a no-cd divination version of the job and the business removed and i know i'd enjoy that style of play.
