The Olympus server is going PvE when WoW Forever launches, per Asmongold, and the reason is simple enough: he says a PvP environment would make the game unplayable for him. His worry is other streamers and their crews. Around 50 people, in his estimate, would be on his case any time he was online, hunting him for fights. He doesn't want to deal with that. So PvE it is.
