I think SWRP is suffering from a similar situation HL2RP was/is in. Too many ranks are donation based - rather than being able to be earned. Additionally most communities are not accepting of new, especially inexperienced, players and often new players struggle to find people to RP with. Another major problem with "serious" and "super serious" RP servers is that there is a lack of events, interesting things to keep people coming back. I remember when I was an admin on a HL2RP server I was constantly running events to keep people about. Problem is that initially requires people to be on the server, coming back to the prior issue of new players not being accepted/able to join in to RP of already established players.
