Accroding to Twitter from @cso_nxj, it was a really sad news that CSO has lost a great server that has lasted for 9 years, "Part of the journey is the end" is an unavoidable thing that this CSO server has to face, the recent amount of players in 2018 is also few, making its server a higher probablity of its closure
Lots of professional players will be remembered such as: OooDa, Zentore (Kzjp), Yasusi,....
Also it is the main reason why Japan server was never introduced in Global Showcase, another thing is Japan is too lacked of famous youtubers about CSO.
I'm not a Japanese CSO player, but as a loyal CSO player from Vietnam (the server closed since 2017) i would like to show a support from all players globally so the japanese will have a bid farewell to CSO
