Again , if you are failing or not you are still only playing a game and you do ZERO WORK , your playing like it or not .
Why do you play? wel clearly for your amusement (or not ?) . Look at the logo
http://eu.blizzard.com/en-gb/ it says "Blizzard Entertainment" not "Blizzard workplace, workshop" . So dont act like your working whilst playing a game , skill ,time and dedication are very different things and they will all differ from person to person . Dont get me wrong i think that people that kill the highest tier (difficulty) should get the reward they deserve for being so good and dedicated to the game they love to PLAY with their freinds .
