By launch it seems to me that a guide to the major changes on the server should be compiled and made so that it needs to be read as the new account is created to let people know about these.
Things such as minor balance tweaks don't need to be in this guide but the big ones really should. Things like PBAOE spells needing LoS to hit, caravans, feathers etc, really need to be front and center in this guide so that people don't roll characters thinking it will work a certain way when it really doesn't and quit because they feel they wasted their time leveling up something that doesn't even exist on the server.
