It might be helpful for the playerbase to know what to expect in upcoming patches, or even pending patches (such as releasing the final version of the notes Sunday night or Monday morning). This would allow players time to find out what is going to change before logging in and things just being different.
I’m not asking for information about exploits that they are fixing. I just want to know that when I log in I can expect my skills to work a certain way. Or that I can expect a vendor to sell a certain item.
