I really liked the concept of Thresh, but he's really bad. I'm so disappointed I can't tell you.
His Q doesn't bring them to you, only half way.
His W is ok.
His E BARELY moves them. It's so useless I'm sad.
His ult is ok.
I don't really care that he doesn't do a lot of damage. He isn't supposed to. He's supposed to take a lot of damage, and move the enemies around so his teammates can kill them.
The problem is he doesn't move them around in a way that helps. He just nudges them along, once every 15 secs.
His Q takes too long to hit the target. If they aren't in the middle of the trail of the chain, they can just run away even when it's coming right at them.
Again, everything about his E is awful. Bad affected area, bad repositioning, bad damage. Doesn't even slow.
Riot, I'm not really a big complainer, but I'm very sad about this guy. You had me really excited to play support and move my enemies around. He barely does that. Please, patch his abilities. He doesn't need to do more damage. He doesn't need to take less. He doesn't need to move faster. His abilities need to be more effective. Otherwise, even with pros, hes isn't viable. At all.
I would be SO happy if you made him useful. I would play him a lot.
