I play on a PvE realm and I suspect I always will. PvP is something I mostly detest, except on the rare occasion. Legion will be launching in a few months with a new PvP system, so I may check it out, but I will never be so into PvP where I move to that kind of realm. As for RP, I’ve never had the desire to roleplay in any setting other than in my own head. Sure, I make up a little story for my main as we go along questing, running dungeons, and going into LFR for the first time, but I have never felt like I wanted to share my thoughts or write a story with other players. For me, that would mean putting more work into the game than I would like to.
I may not be interested very much in PvP or RP, but I realize many players enjoy these facets of the game, and for that I am glad. What type of realm do you play on? Have you ever changed from one type of realm to another?
