400~ Blue, 300~ Red. Way to split up the small community.

200 is more than enough to sustain a server. P99 has been way overpopulated for ages, to the point where you can sometimes sit with nothing to do because every piece of worthwhile content is already occupied. Most of the blue server's problem stems from the fact that most of the players are greedy and antisocial, so the reason it's hard to get groups is because people don't want to group. If you try to form a pug, you just get all the terrible newbies. A smaller population at least frees up some content for guild/friend groups and for soloing.
