They made it very clear they have intention of releasing this on Steam or any other platform. Don't ask about more servers for other countries either; the answer is NO.
Hate to burst your bubble, but all the patches/updates we have were allegedly tested and we still ended up with disastrous results. I don't have any hope they can deliver something that isn't a mess worse than Storm of Arrows ever was.
You would be foolish to hope they can fix this stuff. The reason I say this is keep in mind that all the trash patches/updates they have uploaded(here's looking at you Storm of Arrows) were allegedly tested and you saw how they turned out.
Bottom line: This event is poorly designed and it encourages bad behaviour by the players.
fwiw this is only the beginning, these types of events occur regularly in KR.
