as for what PJ says, I agree. The Greats do seem to have more refinement in their skills than the DGSD Elites. And IMO, doing what YG did was harder than what XF did. For XF's case, all he had to do was just consectuively launch 3 straight palm energies at full force. On the other hand, YG had to perfectly controll his energy so that it would still controll his opponent, but still not harm them. It's like 2 guys blasting a stone with palm energies. XF (DGSD Elites) would be the one that blast the stones flying all over while YG (Greats) would be the one that blasts the stone and make it fall down neatly and in fashion. IMO, the 2nd one is harder since you have to have more control.
