Why don't people play TF support more??? For reals...think about it.
I just tried a norm (obv doesnt mean anything really) and a cait and i rekt bot lane. As TF you basically have infinite poke because of your blue card. In many of the fights that happen early on you can pull up to 3 gold cards if the fight goes on long enough. You can use your ult whenever you are worried about a gank or when you want to see if an objective is being stolen. The only issue i see with TF as a support is that you are very squishy and you don't provide any utility for your adc. You guys should try it out thou, its really fun if you can play TF well.
