Kha'Zix BUG (HAHAHAHHhahaha) When he upgrades abilities/recalls

Hey! So when you are playing and you need to upgrade an ability, you can get it to instantly upgrade by recalling. Steps to duplicate: 1.) Pick Kha'zix. Get 6 youmuu's (optional). 2.) Get Kha'zix to level 6, level 11, or level 16. (Or, kill rengar during late game) 3.) Hit recall and click on the ability at about the same time. You are aiming to click the ability while the recall is in the "pre-cast" cast time. This is where the recall cast bar fills up, instead of getting smaller, it's about 0.25 seconds. 4.) Notice that your ability is now orange and upgraded. Walk around.

How exploitable: Quite, for the in-the-nick-of-time moments. For example, when I'm chasing, and pass a dying minion to get to 6, i can upgrade E really quick (basically in 0.25 seconds instead of about 2.5 seconds) and then FLYYYYYY across to the enemy and delete them with Q. How cool: Very cool.
