or maybe you're just bad with him or don't understand how to play him, he does have excessive amounts of CC and multiple aoe CC's.

Good observation, too bad all the nublets in the world are playing him currently...wait until:

A. People start getting really good with him and

B. When the noobs hop off and people who actually know what they're doing use him frequently.

This is the better source to claim a champion is trash.

Oh, and 44% win rate.
So, yea, he's bad right now.

feeding in three games is a surefire way to see if a champion is good or not.

as opposed to simply being bad at the champion.

A good Thresh is an absolute nightmare to go against.

Maybe you just don't know how to play support?

Then Lee Sin is the most up champ ever, coz i cant do better than 1/7.
Please.

And here I thought you were gonna pull up an overall win ratio. Either way, it'd really wouldn't prove anything. You can account for a bad overall win ratio atm because of the new factor, ergo he is new, so he is popular and unknown, therefore many players will lose with him, giving a false readout on what his actual stable win-rate should look like.

For this case, I'd chalk it up to inexperience to Thresh, play him in normal a couple times more and I'm sure you'll start doing better with him.

I'm currently 5-3 with Thresh. He's pretty damn good once you get used to tiny ass Q radius and when you get teammates that know what to do with the lantern..
