Hi SE, can we get rid of the current card system in next expansion, pls?

I don't think you can have 6 card effects and the seals system.
Maybe three effects and then keep the card duos?

You can just as easily as you keep 3 card effects and have 3 seals or 12 card effects and 3 seals... The one is irrelevant to the other except in that the larger should be a multiple of the smaller. Adding Seals merely down-tunes Balance-fishing to make the other reach breakpoints for viability more often.

Removing the MP reduction of Lightspeed is weird. Essentially it would end up being an AST flavoured "triple cast" but it would be far more beneficial for classes with long cast times, which is not AST's case at all.

Counterpoint: Having MP reduction on a skill that could otherwise be saved wholly for mobility or weaving, where they produce a far more tangible and gameplay-related benefit, is weird.
