So for XB1 our No CP Campaign (Azura's Star) is Dead 90% of the day. I'm sure there are a select few that enjoy playing it, but I never see any population bars.
So why not add a No CP Cap Campaign. If Azura's Star tells us anything its that people want to use their CP even if they can and will be challenged with players at or above the Cap.
Just a thought, I know it's been proposed before, but I don't recall seeing an official answer.
