Ohh we could go on all night with why we play on different servers. I hate that the devs encourage to ganking, which is why I don't play on the PvP server. (and the toxic chat, in where you fit right in). I don't care about PvP'ers view on the PvE server.
The best option is to merge the servers and make PvP something you turn on/off, and severely moderate the chat.
