Nostalrius Begins - Quality wow vanilla realm (1.12)

I had a quick question regarding the pve server.

I read that the pvp server and the pve server will have two separate progression timelines.

Will there be issues making characters on the pve if I already have characters on the pvp server? I only ask because they will be on two separate patches. I could only predict that switching back and forth between two patches may cause my game to crash

just delete WDB to see the dif item stats, or just make a new folder entirely so you can avoid doing that

You will have to delete the wdb folder if you change servers, though syrah said that this would cause a load on the servers, I assume that the only way to avoid that is to have 2 different installations of the game, which is easy to achieve by copy pasting it into another folder with an empty wdb folder and starting each installation only for one server and not the other.

Never heard of any crashes occurring with a faulty wdb folder though weird bugs will occur alot.
