I highly doubt that because half of the skill comes from trial and error, not from actual game play skills. I am sorry but MMOs are just clicking buttons and hitting hot keys, and I have played them all, I even played WoW once for like an hour at a friends house.
Trial and error = rewarding you for playing more. Trust me it is genius marketing since WoW has over 8 million subscribers paying out $15USD a month to play. 8milliong times $15 sure is a lot of monthly revenue. I wish they would go public I'd buy their stock.
