Twisted Fate is more cancerous to play against than Annie at higher ratings
Can something be done to add some skill requirement to his kit? It's even worse than fighting an Annie, because she at least needs Tibbers to get a kill and has to get up close to wave clear.
The main issue is that once he hits 3 items, he only needs to land an auto to kill the enemy carries. There's very little counterplay available to this; if he gets in range of you, which isn't hard during a team fight, you're dead.
His intended weakness is supposed to be his range, and this holds true with unskilled players, but it's pointless against a skilled player. His build usually has him sitting at a constant 440-450 movement speed, which makes it insanely easy to sidestep skill shots fired from beyond your auto range.
He's been hovering between #1 and #2 win rate (along with Malzahar) amongst mids at Diamond for months now, because he has such little counterplay.
