Screens are Plane of Knowledge, Bazaar and guildhall lobby. Plane of Knowledge is still the hub for everything. Plane of Tranq is the hub for just Planes of Power zones. Don't really like hubs and unfortunately, every new expansion has a hub zone. I don't really think of zones as places to travel to anymore, but just connections to a hub. It is conveinient yes, but makes the game world...not feel like a world. I use to love exploring when new expansions came out...all the way up to PoPower. After PoP, expansions became just another level/gear hurddle and not about seeing the new "places"..because they weren't "places" anymore, just connections to a hub.
