This. Also, no log in queue for when the servers are busy. Log in queues I can deal with, because it means eventually I'm going to get in without spamming log in attempts. "Oh, 500 people ahead of me? Well, I'll do something else for an hour until my turn comes up." Come back an hour later, my character is probably ready to play. No log in queue: "WTF?! When I do get in, I'm not logging out for lunch, dinner, going to the grocery store, and since I can't log in tomorrow morning I'm going to just stay logged in overnight."
My concern is the legacy player servers (which in all honesty, were probably player capped and full the first day of early access). Characters from 1.0 were limited to a handful of servers that as of now can't get off or transfer. And in game where there basically no alt characters (because your character can play all the classes, do all the crafts, EVERYTHING as long as they have the inventory space) not being able to log into one restricted server is disastrous. I don't have problems transferring at this point but I want to play my original character, not make a whole new one and start over from scratch on another server. New worlds are great and all, but they don't do me much good if I'm still stuck on one server.
