PvP is always part of MMORPG since man needs to be THE best. But its not healthy since we should be helping one another instead of fighting each other. Even THE SIMS game has PvP, one family trying to have a better house than the other
Think of PvP as a head-to-head sports activity, like boxing or UFC, and GvG as a team-vs-team sport, like soccer or basketball. No drama there in real life right?
Seriously, a healthy competition is good since it motivates people to be stronger, better, faster. But once it gets out of control and the desire for power gets out of hand, then that will become ugly.
PS. I don't participate in PvP but since guild coins are earned through GvG, then I am forced to reconsider joining the ranks of "primitive man" and "his thirst for senseless violence", and where the line "Let us make the fists do the talking
" comes out. (no offense
