Change Talon's E
I think that Talon's E should have the 15% damage increase at all levels, cause there's no point in using it for that early game. Katerina's E does 15% damage reduction at all levels so why not similar to Talon's E? You may say that it also has that minor slow but Kat's also deals damage so it counter-balances that. Buffing his E would also make him more viable early game. He's never played cause the nerfs removed his primary advantage but this buff can bring him back.
