Isn't big support range better?
Is one block placing hard?
Is placing one scaffold 1 block deep in wall such a problem?
Anyway Al will decide.
Hopefully it will have increased support range.
"One block placing" obviously isn't hard, but the point of this is that it doesn't NEED a block underneath - it's fixed directly to the wall.
Placing scaffold IN the wall is at least 2 problems - effectively reduces support range by one, and doesn't look so good from outside if you have one block thick walls.
