Having RDF in Vanilla is already bad enough, since its supposed to be THE open world expansion. It will already decrease what Vanilla makes Vanilla. If the server will also launch as PvE Realm, i would be really dissapointed. It was totally fine for Frostmourne, since it was Wotlk, which is not "open world" focused, but for Vanilla and TBC, it def should be PvP.
Theres so much you need to farm open world, if it cant be contested its going to be a ****show. Imagine Server hits TBC and you cant contest farmspots like Elemental Plateau. Big yikes
