So I went in game and asked in general chat if they knew flying was going to be removed in the next expansion. The responses were all over the place. One person said they knew. Multiple people call me a liar and to not troll. Multiple people started asking if it were true. People immediately started saying that is not true and saying I needed to shut the blank up.
I do not think people know in game. I really don't. I think players in game need to be aware of the upcoming changes. At least be aware of them.
Maybe these players can help blizzard make the right decision sooner rather than later.
