Thresh's ult and it's place in a match.
TLDR AT BOTTOM
So I've always been a fan of using Thresh supp when I'm que'ing up with friends (as I don't trust myself nor other rando's with him). One thing I've always felt though was how underwhelming his ult was and how little it really affected the game. I noticed this more pungently when I was playing against a Thresh and Vayne. Thresh went for a pull landing on me, he quickly flung himself onto of me and used his ult. Besides taking many pot-shots from Vayne I was able to get away almost effortlessly, despite Thresh's ult surrounding me. The slow did make it annoying but that was it; annoying. Later in game during team fights Thresh's ult essentially did nothing. It never stopped anyone on my team from finalizing a kill, it never helped his team secure a kill, and in the end his ult ultimately did little to affect the game.
Has anyone else felt this about Thresh's ult? Maybe does Riot need to do a buff or rework? I'd love to hear some more opinions.
TL;DR: Thresh's ult does little or nothing most of the time. Should Riot fix it?
