I believe a better example of a outclassed champion is Tristana, sure she's a hypercarry with long range but vayne also is hypercarry and has high damage output mid game, tristana not, also vayne has CC and properly played can kite and evade skillshots.
Tristana is far behind from Graves, Vayne, Caitlyn, Twitch, Ezreal, Draven, etc I believe tristana needs a rework, seriously look at his skills;
Rapid Fire (Q): Boring buff yet the most powerful skill in his skillset and the reason why trist is playable.
Rocket Jump(W): Very unreliable escape since while on air you can get hit by anything, still decent skill.
Explosive Shot(E): Useless skill vs champions no damage no range, troublesome at farming because push the lane, serously need a rework.
Buster shot(R): high damage at level 6 then is just a crappy knockback with high cd. By the way Vayne Condenm > tris Buster shoot.
Tristana has 0 mid game pressence, no utility, unreliable escape, useless skill(E), completely outclassed by many carry's.
