Hmmm, if he would be 'extremely pleased' to meet RWX, what would happen if he meets Sweeper Monk? Break down and cry? Ejaculate on the spot?
OK OK jokes aside, I'd bet on DGKB being better than ALL the ROCH fighters. Probably good enough to defeat them within a 100 or so stances. And mind you, you have to be one heck of a fighter to defeat YG or ZBT in 100 stances.
However, SM defeats XYS and MRB in ONE STANCE. And I rate MRB higher than any ROCH fighter.
