I think PvP is mostly empty. The issue is that many do not have time for PvP. I've tried joining maps and often times the PvP maps are empty. Seems like only 1 of the 3 map types even gets used these days.
Here's a good idea... Just like you can do elite timed runs as well as non-timed runs, perhaps you should be able to join practice maps where kills and deaths do not count. So that way new players can practice for some time before they decide to join the real maps that count kills and deaths.
