Reason why pvp is empty is because of gankers and griefers not Xsyons fault, reason why Xsyon said no to merge pvp with pve is because pvpers did not propose a pvp option which dose not force pveers in to pvp, pvpers want to have advantages over pveers and don't want to play on the same/equal rights with pveers.

/pvp flag is a good option, which will allow people to pvp if they want to, but will not force them to pvp.
Xsyon never said he want to remove pvp, he left you pvp server.
