I see your point.
Where do we draw the border now?
Should I really start to describe everything until the last bit and piece in the rules or can I hope for overall understanding the intention behind the rules?
Our rules are not there to play against them but WITH them.
So some blocks around the Turrets is totally fine and some blocks in the ground or half in the ground is also fine to not trigger structural integrity.
Not to mention the stock piles aka Dragon teeth used everywhere.
I hope everything is clear now.
