If I had to choose on 500hrs of wack a mole DDR finger rape (Cata / WotLK WoW), or 450 hrs of auto attack / fuck up and die (Classic EQ) + 50hrs of idle down time, I'm going the 450+50 every time.
Sometimes, after 30min or so of breaking a hard camp, you want that 5 minutes to go fucking piss, stand up, stick your dick in something wet, make a drink, talk to others about how you wish you were 16 eating shitty Totino's pizzas, find some new music to listen to, change whats on the TV, put in a movie, make a phone call, read a forum, jerk off, check the score to a game, send a text, put laundry in the drier, etc, etc, ETC
