I really, really like Egletons, though that +16 Munitions being hit by a US base MG ala Langres needs to be fixed.
The road seems really, really important due to the small size of the map. Not sure if that's good or bad yet. The embankments offered Seb great cover throughout the entire game, and that house whether a FHQ or a shield for a Bunker also seems key.
