This new pick or ban Tristana meta is somehow even worse than the pick or ban Caitlyn meta.
Trist may not be as oppressive in lane on the surface but her all in is a lot better, she snowballs a lot harder, and ganking a Tristana lane is basically impossible. She also scales way harder than Caitlyn so a Tristana that gets rolling is basically unstoppable and your only real option is to 1 shot her; lord knows you can't stick to her for more than a moment with her resettable jump and disengage ult.
, which is really midgame centric. She isn't even amazing with Censer, as she doesn't synergize all that well with Runaans unlike the hyperscaling Kog and Twitch.
