Absolutely not! Tacked on PvP is the worst and its unnecessary. Its like, why can't an MMO just be purely PvE where all races/factions work together, nuff said. Its worked in FFXI quite well for 9 years, sure there is an optional PvP there, but its rarely played, and if you must play PvP, there are some 400+ other MMOs that have PvP in them, so just play one of them.
