That shows exactly what i thought : players cant do a FAQ
I'm not sure that's true in general, but I think we both agree that these players can't do a FAQ.
Anyway, after a couple of more games with Hidden Kingdom cards, my stance at the moment is that it's still far too early for any changes to the meta, even if they were carried out in a more responsible way. 'Standard' decks, especially those based on Wurrzag and Hellebron, are generally weakened through Corb Polybog, and DE mill decks take specific hits from the rebirth of Undead and, perhaps, from Wood Elves recursion with Wildwood Grove.
Let's see how the meta shakes out with the four new factions before altering the rules and creating regional houserules; at the moment there's no obviously overpowered combo, so turn your creativity towards deckbuilding instead of rule tweaking.
