Master Yi's bugged Alpha Strike cooldown with his second hit is still not resolved. [GAMEPLAY]
Master Yi Double hit not reducing Q cooldown[GAMEPLAY]
I'm just echoing a report about this bug a month ago. Again, no complex CoD Zombies Easter egg steps are required to take. All you have to do is press Q as Master Yi and hit stuff. You'll notice an extra second isn't taken off with your second hit.
I've died so many times due to this bug it's practically gamebreaking.
