Think everyone is going about this the wrong way.

Step one: Make pvp not suck. My recommendation would be to revert to pre-endwalker pvp. Loved that.

That's it. Should really cut down on the afkers if the content is actually good.

That or remove all the achievements and rewards/tomestones from it. That way the only people in there are the ones that want to pvp. Ques might take 72 hours to pop for one match, but hey at least only the truly committed players are there.
