Dragging and dropping cards/character icons is not only a chore, but it's also the source of some issues for players currently. Either phase it out completely or allow for touch inputs in succession to accomplish the same goals. Nothing is gained by dragging your finger across the screen countless times, it is only added tedium - especially when discarding multiple cards in a row. There's no novelty or flare factor gained from the obvious reminder of the magic of touch screens, it just feels clunky and disruptive to what is otherwise a smooth experience. It's about the only complaint I have about the game right now. And in generally it's one of the worst aspects of touchscreen gaming as things currently stand.
