Why do we have Negative thread for a pack that is not yet released?

Because as people get excited with trailers and the release of the blog post with descriptions, people also have concerns. So it’s good to have threads that separate the two so they don’t mix up.

Basically this.

Also the "Negatives" threads are actually very useful for the game team for both tuning and future content updates. Even if the issue is that you hated the trailer, it's good feedback to have for our marketing peoples.
