Good betatesters and good artists are often very different people. Qualities required to be a good betatester (meticolousness... precision... adaptation to boring and repetitive task.... methodical mind) are often not the qualities of artists (creativity... improvisation... illogical solutions). I think we shouldn't hit CL on this one. I don't know if it's true, that many people in the testing team were artists, but if they were, now CL sure has learned the lesson and next time, they'll choose more amongts the people in the forums here who displayed a more technical-methodical attitude.
