What is Thresh's weakness supposed to be?
As I understand Riot's design philosophy, champions are supposed to have clear strengths and weaknesses. What I can't figure out is what Thresh's weakness is supposed to be?
Mobility? He has a huge self-displacement (not to mention the enemy displacements).
Damage? It's not high, but it hardly matters with his lockdown CC and tankiness. He gets free armor, so he can focus on MR.
Sustain? He has a relatively spammable shield and he doesn't even have to trade shielding for dragging someone to him.
Also, after reading this, I just realized that you can say nearly the same thing about Lee Sin (though he did lose the shield when ward hopping).
