Long-grind Lennys tend to MMO hop looking for that fix, though, while Casual Carl usually sticks with an MMO for a while because the stuff that matters to Lenny doesn't really matter to Carl. If I was SE I would probably cater to Carl as well, given that Carl is going to pay his sub longer. Unfortunately this does create a vicious cycle in which companies cater to casuals because they keep paying and don't realize that Long-grind Larry wouldn't quit if there was more for him to do.
