and to be fair (going by that reasoning), in the moment the new FAQ release (Core Rules) will include again also that specific Q&A, at that point it will be more recent than our battletome, thus overriding it

I'm thinking the upcoming GHB may include some updates on this seeing as how faction terrain is quite common now. I'm just hoping it's well done. Remember how last year's pitched battles' terrain portion was pretty much rewritten in the following FAQ? Lol/smh
