Item drops & resource drops are the reason why transfers have been turned off. I have around 300 werewolf transformations and 600 PvP halloween candies because of item dupers duping suspicious crates and then droping them on death.
No doubt the people on Crom wouldn't like it. The PvP community is toxic, full of trolling and general douchery.
This is probably the most feasible solution. Merge everything into one server, make it an option to enter a PvP instance (like epic instance) and then give PvPers their own chat channel. Then non-pvpers don't have to listen to the garbage.
And since there is one server, at least one GM can monitor chat at all times to make sure the PvP trash talk stays out of global.
PvE server is the most populated. 85% of the remaining pop is on there (random numbers pulled out of ass). Forcing them to PvP would be very bad and would probably kill off the remaining pop.
Optional PvP instances like Epic instances is the way to go imo.
