Tbh, i dont think this will work, those lines you came up with sounds so childish not even other children will belive in it.
You can ofcause change them, but its like the tiger scam, just even worse.
Many noobs have only heard the word "Catalysm" and have no idea its a new exspension. People who know what it is, knows those beta's doesnt exist yet aswellSorry but i doubt this will work.
