Hecarim E

I've had a number of games where I would use my E as Hecarim and as I'm directing clicking on the target I wish to hit, Hecarim will then target an entirely different target. I had rewatched this multiple times on my games and it happens occasionally, but enough to make a difference and each time it happens it leads to a major death. Is there some sort of @override in Hecarim's code for his E that negates the user's directional || target command? This is honestly so aggravating and it's turning me away from wanting to play Hecarim, even though I enjoy him.

Could I get some insight for a dev?
