I've not heard or seen any type of announcement regarding these rewards other than what they are. We have been told that we would be given a class mount of our choice and a free race change. Everybody I've asked only says these following messages are the only messages regarding the beta rewards;
I've been active on Discord every day, I use Discord on my desktop and my mobile, so I am always connected. I also vote daily for Monsterwow, so I also very frequently visit the website and sees whenever there is an announcement or update on the frontpage.
Yet, I have not seen a single announcement, nor can I find one now that even relates to any beta rewards.
So I now wonder, when will I, and many other people, get their rewards they were promised?
