Granted, right now, most of our PVE content may not be as exciting as compared to when playing against a player. However, if done well, bosses and other mobs can be quite challenging too. We have seen it in many console RPGs and we are seeing some new MMORPGs giving challenging boss fights and not just extra HP to prolong it. Given the rise of Action MMORPGs right now, I believe that challenging and exciting PVE will be greeting us pretty soon. Also, if a heated battle against players is what certain players want, other genres can better provide that. MMOFPS and MMOTPS will not require you to grind since you can just immediately play against players. MMORTS also lets you battle out your wits against other players. These genres can better satisfy the competitive nature of these people. MMORPGs are still more on the PVE aspect. The PVP aspect was added so that some players who are into PVP, will also be enticed to try the genre, thus, increasing the market pie.
