So I don't know if I am the only one or not but the card system is a little...annoying to deal with. Even more so with the change of faction points into talent points. I do enjoy talent points because now I don't feel so restricted whenever it comes to playing the game. However, there are a ton of cards I have been trying to get. For example: Ginebra's card "Thrusters". I haven't even gotten the common version. Sense there are SO many cards with the so many characters it is difficult to actually get desired cards. I find myself getting the same exact cards way too often as well.
I think a good way to change the card system is making the cards purchasable like the guns in the games. Say rare blueprints are a 80k talent points while the commons are like 12k. The numbers of course not set in stone MSE can change them to whatever they want, the point is rares cost more than the commons. I don't believe this would break the game because it gives more wiggle room with experimenting and it will make getting cards less of an annoying chore.
