SotF thoughts on Barricades

[Morgolon]

Hi,

Played a bit SotF and been looking at the barricades. Lots of fun and great for heroes. While safe for a while, when you surround a building with your zombie horde it makes heroes sweat

Just wondering if adding barricades to some of the "old scenarios" wouldn't imply reduce the number of casualties needed for zombies to win by 1.
Could be a Dot rule costing the same as Barricades.
As most of the new scenarios only need 3 heroes dead.

And which scenarios shouldn't use barricades rules to keep the balance?

Obviously I wouldn't allow barricades on defend the manor house, this scenario must be the nightmare of all heroes (maybe I should test anyway)

cheers
