One of the best pve MMORPG game for me was Raiderz, but I do not know if it still exists.
For just grinding there has Lineage 2 and Metin 2 for example, but i dont like thier pve features.
@Frammshamm explain the point very well.
I want to add also that the pvp is faction vs faction, and if you go into the enemy faction area(except sea and war zones) you cannot attack your opponents until they attack you first.
