How about a quote that states:
Know that imbalance is actually bad. The first thing that I think everyone has to do is to internalize the idea that balance is good, and imbalance is bad. I've actually heard people try to argue that a little bit of imbalance is necessary for a fun game. Not only do I disagree, but I think that they don't even really believe that. Someone who says this is simply failing to see one of two factors:
1. Like I stated earlier, there are sometimes elements that seem imbalanced when looking at one level of scope, but when looking at the whole picture are actually in balance.
2. That a game can be "fun" whether or not it's balanced -- the word "fun" is a notoriously crappy metric. Anything "can be fun" with the right attitude -- flicking a dust-ball around on the floor, brushing your teeth, anything.
If a game is fun despite being imbalanced, that's great, but do not make the mistake of thinking that it's fun because it's imbalanced.
