I actually heard that CDnF PvP videos weren't reliable because they lacked alot of patches which helped balance PvP and kept people from doing some of the combos you see in a few of the "Can you play this game?" line and other random videos. Same person told me that DFO came with these pvp updates already in place.
At first I didn't believe him. But I saw a video where a WM didn't seem to have a cooldown on his Secret Slayer Tech, so I'm guessing there must be some truth.
