Why does caitlyn have an early game and a late game?

don't tell me about the mid game power drop. its bullshit. caitlyn winrate is 52% at all points of game . 2 zeal hurricane ie caitlyn is the best mid game ad carry in the game. Why does tristana have such a shitty fucking early game and mid game. only to have a late game that is WORSE than caitlyn's. Nerf headshot early game damage. or headshot late game damage. this is absurd. 30% playrate. 53% winrate. ezreal and lucian barely had 50-51% winrate when they had playrates that high. why are you allowing this?. I never go bottom lane because of caitlyn. last match I autofilled. against a duo q bot lane. morgana snares. caitlyn puts trap. triple headshot does 500 damage at level 4. wtf?.

if we can complain about yasuo doing the same thing. why not caitlyn?.
