Ok so everyone is out getting their new 6ed core book. Lots of good stuff in there. I don't know about you guys but I keep finding myself lost in the fluff / modeling pages. But as you are digging through the 130+ pages of rules remember to go and pickup your FAQ off the GW site.
Some tasty tidbits:
Most winged upgrades give the WMC unit type.
All nid psykers get to replace all of their powers with the new cards. One for one. That means the swarm lord gets 4 cards pulled from the pile. I dont know about you but a 66% chance to jump the tuff/str up +d3 is very very good. (Tuff 9 nids = OP)
