Camille needs the Irelia treatment
Nerf her cooldowns and increase her mana costs, boom you have a somewhat balanced champ now.
Her Q's mana cost is rediculously low for how good it actually is.
It should be 60/55/50/45/40 and the CD increased to 11.5/10.5/9/8.5/7.5 In addition her Q should NOT turn Trinity Force Proc's into true damage.
Hookshot/Walldive should be 70 mana at all ranks, the CD I believe is fine.
