to be honest, its an interesting feature but not a very efficient one. I mean you spend points for a card in your deck, maybe more to reshuffle and for what? you can only use one card out of the 4 that you can hold so whats the point? once I have the best card, the other three become obsolete. it would be different if all four cards stacked in away that gave you some sort of customization or strategy but they kind don't because you can only use one.
I can see how others wouldn't like the shuffling, bad RNG on your well earned faction points and all that. Why not just keep the card motif but change how they work? let people make decks that can do different stuff and have them stack. Maybe have different hands for different tiers of cards. Like maybe you want to load a super powerful deck to make a character stronger or faster. OR maybe you would rather make a deck that gives you more rewards? like more gold, or faction points? heck even item cards like an aleph reserve, or special ammo.
To me, the current card system should change because eventually. you will get the best card and by then faction points and even the card system become unimportant to the player. they would just start sitting on faction points not doing anything.
