Twisted Fate quality of life idea - Making the W less frustrating
Ok so TF's pick a card is a strange ability, requiring you to wait to recast it when you accidentally miss the card you want, or if the card you want is the third one. What if instead of needing to recast it, it worked like this:
W - Pick a card: When TF casts pick a card. gains an indicator over his head marking that he's using the ability. During this he can cast Q to pull a blue card, W for a yellow card, E for a red card,and R showing a "white card" that's just to cancel out of it. Depending on what card you picked (except for white card) that card was above your head showing which one you picked.
This way you can instantly choose which card you want, or if you want to cast a different ability, you just click R. For any balance problems maybe give him a short slow or channeling time to pull the card out. Just in case the "waiting for a card" being removed becomes too strong.
