Aurelion Sol's Comet of Legend "Walking in range"

Can we change this to going off in the target direction instead?

While I'm getting pretty good with him and I'm loving having a new roaming mage - I've failed the "Lissandra gank" (next to red side bottom tower, or blue side top) too many times and it's frustrating as hell. It's always the same scenario - I wait for a good opportunity and then click Q+E, and with my camera over the lane I don't notice that Aurelion's fired his Q and then started walking around.

A second issue - what the hell is up with the recast time on his Q? Sometimes I can instacast it - sometimes I can't right up until maximum range. And when I say sometimes - I'm being polite. It is frustrating as hell watching my Q sail right passed the Xin Zhao, Alistar, Lee Sin, etc, in my face... if it has to travel a minimum distance, please mention it, and please make it consistent. (A bug report while I'm at it - the damage and stun aren't applied at the same time, and characters visible move after taking the damage and before being stunned.)
