Does a model recieves damage if it only could be driven back to the edge of the board as part of an attack action? It seems quiet locigal for me, but I couldn't find a passage in the rules which says so or clarifies the edge as occupied or blocked hexes.
On the contrary the following part of the FAQ (1.2 p2) suggests that the edge counts NOT as blocked hexes.
Q: Does the edge of the battlefield block line of sight?
A: No. Line of sight is blocked by blocked hexes, but not
by the edge of the battlefield. However, when counting
hexes to see if an Attack action is in range, you can only
count complete hexes.
Note: I'm using german rules so there could be some problems caused by the translation ... or my english
