A big slew of class, interface, guild and content changes are coming in patch 4.1 which lands on servers this week. You might want to familiarize yourself with them now as they will be reality tomorrow
http://www.mmo-champion.com/content/Among the great changes are that knock backs (ele shamans and resto druids) now interrupt "worshiping" on Cho'gall and some damage reduction on Nefarian.
There's also a very cool guild finder where guilds and players can create a profile for who they are and what they are looking for.
There are also a new series of guild challenges for guild groups to complete together and for which guild XP is gained (we're almost at 25)!
Perhaps best of all, your 'daily' heroic is now a 'weekly valor point from heroic' cap. This means you can do ALL 7 of your allowed 'randoms' in a single day, over two or three days, whatever - no need to log on every single day and do a heroic. Instead you get credit for '7 randoms per week' rather than '1 per day'
