I don't understand the purpose of this test at all.
After all, the beta test has been officially extended.
And this means that they will show some kind of staged, promotional version of the game, which has nothing to do with the actual game. It's just a clever marketing trick to show how great everything really is and how transparent we are.
But in reality, even the magic system hasn't been released yet. And that means that work on it isn't finished.
In my opinion, it's an attempt to put on a good face when the game is actually bad.
