Is there a way to leave a PvP map at all once the match has started?
I was playing a Challenge PvP in Shanty Town and we found the only way to leave the map was to complete the mission, there was no 'warp to sector space' or beam up option. I tried logging out and logging back in but I ended up back in the match.

If there isn't actually a way to leave PvP matches other than someone winning, and if there is not can this be put in please? Obviously there should be some kind of penalty or a 'quitter' debuff is this happens to prevent people just going in and out of pvp matches constantly to find a prefered match.

For Space PvP, you can fly out to the border, but for ground PvP, there is no equivalent option: The ability to leave PvP matches was removed to avoid certain people from leaving the match prematurely and ruining the game for the rest. (So it existed at some point).

I think you can leave by logging out but you need to wait a few minutes (logged out) for that to work.
