Simple solution.
Remove gear. Everyone has no stats, no mitigation, nothing. Just lightsticks, sticks, and blaster sticks.
Not enough?
Ok, also remove deaths. People can't have fun being dead right?
Lessee, I already said remove gear
Oh, remove fighting. Some people don't enjoy fighting, and because they pay their subscription then should be able to enjoy the non-violent aspect of pvp too.
Now that everythings set, let's all hold hands and sing Kumbaiyah.
