Why is Twitch so bad?

Hi all.

Adc and jng main here, so naturally I play ranged champions. I haven't played Twitch on WR in along time, I tried him out today and oh my God what even is this champion.

Played in ADC and Jungle, probably troll for the latter but I genuinely can't believe how weak he is.

He's good late, but any good team will make your early unplayable and by then it's already too late, even if you are ahead by some miracle, you are super immobile and AA range suck.

I dont main twitch, or play him, but I feel SUPER bad for anyone who likes this champion lol
