What if you wake up one day and WoW is free to play with an in game store you can buy custom titles, custom mounts, transmog armor and weapons, pets, race change, faction change, EXP bonus', Rep bonus', Honor bonus', etc
What would you do?
Me?
Well first I better get some "In game credit" for being almost 8 year WoW player.
Second probably not care and keep doing what I regularly do when it was Pay to play.
