I have just picked up 7th edition, the ork book and the Ghazghkull book. coming from 6th with a good understanding of how it worked I can honestly say I dont have a clue how to write an army now.
q1. can I take any detachment as a primary detatchment so the combined arms from p122 of the rules, the hord from the ork dex or the great waaagh from the ghaz book. additionaly I can then take any other detatchment I like such as the allied detachment or a combination of ork detachments.
q2. if I take more than a single detachment do the benifit from there individual detachment rules?
q3. formations... how do I take these. the rule book says they fit into normal force org slots. however most of the formations in the ghaz book wont fit into a detatchment. I cant take that much heavy support / HQ in a single detatchment. are they unbound (ie useless) only, as nerd-rage prevents unbound lists in all clubs? can I shoehorn them in across two detachments? ie the 5 battlewagon formation could this be spread between detachments
nb: I have searched I have googled - no joy
