Hypothetical threads like this got 0 value. Absolutely worth nothing - it worth a piece of paper from the trashcan. Otherwise I would also love a Fifa game, but the teams would consists of WoW characters.
The problem is nobody considers what's possible(techinical), do people actually want it(community needs)and does generate money for Blizzard.
I would be classy, if people would consider these(among other subjects)before posting. Just ask the question - why didn't we recieve it after 18years?
