All it takes is a bit of imagination, creativity and not being a square.
This is the way people RPed in games from time immemorial, because what you gonna do - games are limited, so you fill the gaps with a bit of imagination and whatever you have available.
But sure because it's WoW and Blizzard did it, then it's some sort of sacrilege to do what we were fucking doing for decades in dozens of games, Blizzard or not.
