Nah, Old School Runescape is a much better game with a bigger community. play that instead.
While i respect Runescape as one of the more popular free to play mmorpgs, World of Warcraft is on the different level when it comes to absolutely every aspect of the game.
Runescape is a free game that has maybe 50-100k thousands active players, while World of Warcraft has 4-5 million players that are paying monthly fee (10-15 USD, depending on region).
