Well if we are going to force PVE players into a open world PVP zone, then why not just add a part to HM- TFB also i mean why not makes sense right ? There's some droids in there it would totally fit the story to have parts only available inside.
It would stir up the RAIDING part of the game! And there would be all these new people that want to raid all of a sudden. If someone really wants to get HK they will just get a pug together and raid, or not participate in the new content. There needs to be a requirement for EVERY part of this game to be involved for this quest ! I mean its optional may as well make it so people don't even want to bother with this new content.
