Well having just leveled an alliance character for the first time since BC I did get lost quite a few times and I did have to figure out by running around (deliberately did not look anything up) where the heck things were and how to get places, where do the boats go etc.. I quite enjoyed it. Not sure what you mean about not having to cross the world? I was constantly wearying of the travel on my gnome, got spoiled with the main having all manner of doodads to magically take her to the varying spots.
Yeah the Broken Shore scenario is not for fighting, you could just stand there and complete it. It's not designed to be gameplay though I don't know why that is.
As for community you see more of your own server in the main cities as far as I can tell, outside of them it's all pot luck. Distinctive servers are still distinctive in my experience, but yeah you don't meet people out in the world and make friends, you meet them in trade chat, SW/Ogr and guilds. I certainly do miss that.
