FAQ/Errata up for Skaven/FEC, on their FB page now but hopefully up on the site soon. Mostly randomly obvious answers ,as these have tended to be (what's d3xd6?), but one thing is that it clarified the rules for Gristlgore. Royal Terrorgheists and Royal Zombie Dragons in Gristlegore are no longer Behemoths, so you can take more than 4 if you use that Grand Court. You can run 6 models as your army, and be legal. That's pretty amusing (but probably terrible), a small change is that it means those models can start 9" away from enemy territory on Escalation. Not overly powerful, but pretty cool.

The fact that the Gristlegore General that fights first (twice) and murders everything it touches is unchanged is pretty jarring, though I think the mid-year FAQ might change it if they start rolling through every tournament between then and now.
