In his first 3 series starts with XSET, Zekken has averaged an insane 310 ACS and top-fragged all but one series, in which is came second in ACS only to PureRs' 343 ACS. All aboard the Zekken hype train!
It seems to me like they weighed their options and chose wisely for the most part. They even gave Thwifo a semi-decent parting message in the form of a "thank you" tweet. At the end of the day, organizations need to make tough decisions like that to improve.
Agreed, I believe he has some limited experience on Sova as well in some of the VCS matches. I understand those are basically just PUGS but it was still fun to watch him frag out on a non-duelist character.
