FreshServer
The population is very small and dividing it into 2 servers seems like a bad idea to me, unless it is possible to transfer characters through servers.
New PvP Rules
I think it's a very good idea to divide pve and pvp players.
The most played MMOs do not force players to fight with other players.
But players who want to do pvp should have some bonus for taking the risk of losing their inventory (example 20% more gold)
