I understand most players are teenagers but this game is 13 years old now. Consider there are 2-3 more expansions left in wow (4-6 more years). You can have teenager kids approaching wow playing age.
As a parent, will you let your kids play wow?
edit:
If there are parent players (weird combination tbh) browsing this thread, are your kids showing any interests in wow? Bliz may be doing everything they can to advertising hearthstone to new generation but it should know wow's like cigarettes, most of us are attached for life!
