Just nerf Camille's laning phase.
All they need to do is remove the sweep heal on minions and move the heal proc to the inner cone instead of the outer cone. It's not fair how I'm chasing her, or she's chasing me and she's able to W with no risk while heavily slowing me and healing. Move the Q movement speed to her second Q only. She already has a shit ton of sticking power. Also remove the "homing" on her Wall Dive stun.
There she's balanced.
