Personally, I play both because I enjoy both sides, and am free to switch to one when I'm tired of the other. I'm getting tired of reading posts (especially in #Feedback) that say only a tiny amount of people care about PvP, and with generalizations that every PvPer is just a bored CoD nut. I believe the game's population is far more balanced than it's given credit for, and I feel that recognizing that is a first step for the estranged communities to stop attacking each other and focus on providing Bungie with thorough feedback as to what we want to see in the game.
