Kassadin changes feedback

As the change says Kassadin's E cooldown has been decreased by 1 second. My suggestion would be to keep the cooldown the same, reduce its required spells cast and add some base damage to it. Riot, the problem with Kassadin isn't his late game, which is why increasing his ap ratios is not necessary (as you did with his ultimate). Instead, try adding some base damage to fix his early game/mid game problem that you've suggested that way the buff would solve it. Adding more power to his E as it is the least-often used spell in most cases would be the best option imo. What do you guys think?
