So what happens when you are lolrp'ing out in the open world and a group of opposite faction (or however they're labeled) happens upon you and sends you to a spawn point? Are you going to march out to where you were by yourself? Hope that someone invites you to a group for some modicum of protection? What happens when factional balance gets out of wack (and it will).
I really don't get your view... I'm sorry, I just don't.
There will never, ever, ever, ever, be an MMO designed that will do anything but ENCOURAGE grouping... That's the genre. If you want to solo your way through a game, then I suggest when you shop for your next one, use the little filters and avoid anything that says 'multi-player.' Otherwise, I suggest you roll a stealth class, AND STOP JOINING INSTANCED PVP, to which you seem to have a very real aversion.
