You need to be on the ground, not inside a building? You can't place a wooden stake in stone after all. Also they can be destroyed, they are only dangerous if you don't see them on time and walk into them, or if archers are trying to delay you while getting shot.
Well I meant on the ground level. I'm thinking of that one spot in the central ruins in particular, where there's only one way up and it's up a narrow flight of stairs with walls on both sides.
At any rate, if they were destructible then I'd be okay with it, from an infantry point of view, I think. Though I'm still wary of making them any more anti-cav than they already are.
