Why dont people Dragon PQ?

People don't PQ just for experience.
Kenta's Goggles and Von Leon Belts are far more useful, for most people, than anything you can get from DRPQ.
Although I must say that my alliance's PQ-enthusiasts group used to do all four (Kenta, Escape, Hob, and DR) every day, for a good long while.

I'm quite aware of this, however I usually only see people do kenta and hob pq in kradia usually, rarely doing escape (gonna guess it's because of the jump quest) and drpq (gonna guess it's a combination of fear of the damage reflect even though it has been changed, the d/c bug, and the fact auto hp/mp cannot be used in the pq).

I just wish people would do drpq and escape more often, because I find those two pqs to be more fun then the other two.
