If you decide to leave your gaming career behind and sell World of Warcraft account or characters it's probably a good idea to figure out which characters might be the most valuable and which will get you the most money. The most popular classes played in the game are paladins and druids although the lesser played classes, such as warlocks and rogues will fetch a good price if they have nice gear and additional perks like pets and mounts. The great thing about selling a character is that even if you decide to come back to the game, you can always play again and create that same character anew.
