Fury is healthy.
If pvpers transfer to the pve server it will be really sad and they'll miss out on duels, occasional open world pvp (the merges could bring some more frequent open world pvp), Bori farmers struggling to dig cos they get ganked and overall much better pug minis. Don't go on a pve server and then complain about how pug minis suck and how open world pvp is dead, please
I do like the idea of a single server but there's no perfect solution IMO and FC is most likely not going to do that. Cross server tech would be great though
