Oh I want the walls to definitely keep the seen requirement. I think that's the main balance improvement from the good old days. Just think the unseen enemies requirement is really weird and artificial as far as actually using that boon goes (basically, it's useless except for late-game converters to Binlor, and even then it's pretty niche) and the walls requirement is a bit excessive now that Stone Soup means Binlor players get less of them to play with.
@Wargasm - yeah, that's pretty much my experience of poison.
