During the finals match between MVP.Black and Virtus.Pro at the recently concluded IEM Shenzhen, it appears that the former may have intentionally exploited a bug to gain an unfair advantage.

To quickly summarize the bug, it works like this: First, Zeratul activates Shadow Assault, which allows him to jump to a target. If the player can start the dash to the intended target, then click on a new target before the animation is finished, Zeratul will be able to dash to the new target, no matter how far away it is. This is most certainly a bug, and one that helped MVP turn what appeared to be a 4v5 fight into a 5v5. You can see the minimap here, which shows the unnatural movement of Zeratul.

Given the extreme reaction time that's needed to utilize this exploit, it would seem unlikely that this occurred accidentally. ESL caster Kaelaris actually commented on the issue, stating: "We're investigating, i've passed on the information and my thoughts to our League Ops - but from what I can see without going in to too much detail, it looks intentional."

This doesn't look good for MVP.Black. While it's certainly not unheard of, intentional cheating/exploits are never good for any eSport, particularly one just starting out and looking to find its footing. Given that the investigation is still underway, there has been no official announcement or punishment. We'll have to wait and see what the final result of this will be.

For those interested, here's a demonstration of the bug:
