Well if the defense stats of rivals doesn’t match what is showing on the profile, doing an pvp going to raise a lot of complaints. Furthermore the equipment comes into play which is not displayed at all so it could become a chance event for win/loss. Either Gree is trying to address this or maybe some other problem on the game platform (Like memory and loading issues) that’s delaying it. Personally I like the past pvp event, but presently there are too many events running leading to player fatigue and frustrations, so prefer if they drop something before adding a new event.
