So this guy finds a spot in the world where he can guarantee himself some pvp action. And you, having willfully rolled on the "stand-up-to-pee"-vee-pee server, need an option to avoid pvp at such time as you feel you need. Sorry, but frankly I like the idea that bioware is forcing the issue here. If you want pvp fine, here it is, dont shy away from it. You rather he jumped you while you were half dead fighting some elite out in the field or something? Either way he has the upper hand, just this way you either must beat him yourself or get a hand to beat him. Or log on an alt. Or join the right server to start with. You have options.
