Big Bang, Chaos, What now?

I don't see anything wrong with taking only content from KMS. That's largely what every version has been doing for the past 7 years. They're just localizations, after all. Non-KMS content is generally poorly designed and unbalanced.

I don't see how you think they can hit a wall by doing this. By that logic, KMS is constantly running into a dead end. As long as you are getting content directly from a game that is actively being developed, the wall just keeps moving further away.

And what if KMS stops for a couple months and then we catch up? We're not gonna have any filler patches? KMS never runs into a dead end because it's the lead developer of MS. They can make any content when they want and how they want. We on the other hand can't just pull huge skill updates and game changes out of our asses. So yes filler patches such as wt and exclusive content are needed for outside versions.
