I'm loving the new book if for no other reason then it makes the army interesting again. Definitely not the new power army but that just means I won't have to see 50%+ of the 'fair weather' players at a tournament fielding Eldar.
First build I'm going to test out is Jetbikes and Serpents backed up with Fire Prisms and Nightwings... sorry Crimson Hunter. Actually the first time in 6th I've considered a mech heavy list viable...
