What if Caitlyn did less damage at short range?
Like, if she was melee range she does 50% dmg, scaling up to 110% at VERY MAX attack range.
That was she cant just stand still and auto in teamfights while lifestealing all the damage she takes back. She'd actually have to position and kite well.
This would also make thematic sense since snipers are more powerful at long distances.
