Aside from FPS games that require it, IE TF2, CSS, etc I have never played online games purely to fight others. I have played months of mmo's and in one particular example have only done pvp 3 times over the course of approximately 174 days of ingame play time, all for about an hour total. I hate in mmo's where you have to make a decision to do PVP at the very start and therefore miss out on the pve content because increasing your defense makes you weaker against other people. I prefer to do everything and even being near the level cap on said MMO I still get killed before I see what happened because of people who are designed purely to kill me. The only way PvP is ever fair in my opinion is when two people have the same equipment and stats, therefore making it a matter of strategy instead of go kill cows until your numbers are better then his numbers and come back and click the shit out of him.
