Why not just use your human resources from youtube / that community of yours and make some kind of PKing events? Our main problem is that every pker who joins, either sees the empty wild and leaves or just afk's at bank for 8 hours to do a quick wildy run for 15 minutes. If we can manage to get a big chunk of pkers to join and fill wildy up, we'll be fine.
No additional content will help with wildy numbers.
