I don't see how me not liking the idea of a GCD card system because I feel like it would be clunky or change the way I play the class to the point where I will likely switch to something else = I don't want any changes. I don't like your idea of a card system. That's it. There are plenty of ideas to change AST's card system that I both agreed and disagreed with.
I told you why I didn't agree with it - I like the feel of weaving the cards as they are and that we don't need to have them on a GCD when we had them on oGCDs and can keep them on oGCDs as they have been for 3 expansions right now.
You can either take the feedback and adjust your design or ignore it because you think is fine. Its your opinion like mine is that I would hate your idea of AST. It has nothing against you as a person, so I don't know why you're making it seem like a personal attack here.
Back on to it I suppose is the best way that I can describe your preposed idea is going back to 5.0 cards where we had to change a Major Arcana to a Minor One with all the animation clunk to begin wtih - (Draw - Change into Crown - then Play) and if that's how its going to feel, then no. AST is far from perfect, and the APM is probably too high, but I don't want to go back to that levels of clunk.
