As a DPS player that loves to push myself, I'd love a DPS check to be in all content. However, history shows that when normal and msq content is made more challenging, a lot of people will quit. Financially, that wouldn't be good for the game's growth. It would start to die out. I remember when people would get the Pharos Sirius dungeon back in the day, and leave the instance immediately because they don't want to deal with the difficulty level. At least we still have them in Extremes, Savage, and Ultimate,
