it was... interesting.
The speed and precision of the Xerath spells were so much more than I was used to and I watched worlds 2014, 2015 and 2016. Also he used summoner spells and items incredibly quick and precise.
This guy has a 88% winrate as Xerath in 25 games, yet not enough games to show an MMR on op.gg. He topped Gold and Damage to Champions easily exceeding a Zyra, Cait and Illaoi.
Anyways, like the good guy I am I did a ticket and a report :D
