Cross Realm

I wanted to ask if it would be possible to make add friend work for party members that I met on a party finder. I had a chance to meet lots of nice people that I wanted to add them or they wanted to add me but it wasn't possible. We had to exchange our info outside the game within different app. I was also wondering if it could implement a system which transfers all cross-realm party members to less populated server that would be picked for that temporary period of time to enjoy content together(not instanced dungeons or raids) Otherwise making friends through pf is kinda hard. It sounds like it's impossible to make but I thought it wouldn't hurt to ask. Also cross realm free companies. Would you guys be happy with such system if it would be possible?

There was word that this was going to happen sometime in the span of 4.X, but no details on when... at least I don't recall. I was wondering the same since I've been debating on a server transfer =/

I'm pretty sure it would make server transfers easier. Without loosing your friends.
