Just to let you know, the FAQ's are up for 6th Ed:
I've just had a glance through them before I head out, and a few things to note:
Space Marine Combat Squads split before deployment, and then count as 2 separate squads. However, each of them can ride in the same dedicated transport (so Rhino's can carry 2 squads of 5 men.)
Most of the Area Buffs have been re-worded so that they only affect the Codex they are from (no, you can't ally Blood Angels and get Feel No Pain/ Furious Charge on your Space Wolves!)
There isn't much Mastery 2 or 3 in the game. Eldar, Grey Knights and some Marine Chief Librarians (note- not Ezekiel, sorry Dark Angels) are mastery 3. The only Tyranid with Mastery 2 is the Swarmlord- everything else is Mastery 1.
I'll do a more complete when I get back, but for now I'm off to play me some 6th Ed.
Comments, as always, are welcome.
