Clearly kj fked up by overrelying on turret to check for 2 chokepoints (garden and heaven)...
Also any kj player knows that the turret has a slight delay upon identifying and shooting the player and has a 3 shot burst. Omen was identified, but as soon as he was identified, he ran behind a wall, so the turret shot its 1st shot at that wall then repositioned to its normal placement and finished its 2 shot burst. Then, Omen swung and destroyed kj turret during its delay. It was just incredible timing by Omen and poor turret placement by KJ. How the hell was that a bug? If this was, indeed, a bug, then KJ's turret needs a complete rework as it worked as it had always intended... I think someone on Riot was just a huge fan of Xset and/or Riot wanted to push the DRX vs. Xset rivalry so the arbiters gave biased judgments in favor Xset. Either way, this was not cool at all. Fortunately, the proper victor won in the end.
