So once MS2 is released to KMS..

You know, there's really nothing to argue about here. The game does not tell you to follow a specific build. Nexon does not care if you go statless or not. Sure, the game is set up with a two stat build in mind, but people will always powergame, and make the most efficient use of what they have. There's nothing wrong with that, but keep in mind that Nexon is under no obligation to perpetuate the superiority of the currently most popular builds. The "most efficient" build can change based on their whims (though hopefully the changes lead to a more diverse, balanced game). That's really too bad if your current build is screwed over. Get over it.

Warriors are a one stat class. Dex is not a secondary stat for Warriors.
