It shouldn't have changed. That note was from an early, admittedly somewhat sarcastic response in reaction to a request to add naval to over half the maps that was part of an earlier plan. We'd refined our view of it based on gameplay and history to arrive at the current plan. I think we're at a solid compromise between the two that makes sense. The item accidentally got added into this list because I'd copied from all the update lists since the official release and missed this one when I went back and weeded out the items that were not pertinent. Hey I was in a hurry.
I have to say this (I think the allies have unfair advantage as it stands now so I am not crying for extra offshore support, well maybe after you read this I am ) in the GC with FK we had this exact meeting, 12thSS fighting Canadian troops (8/3 in our game) between Caen and Bayeaux (at Buron) on June 7th (same day).
According to the militaryhistoryonline.com, a combination of massed artillery fire and NAVAL GUN SUPPORT quicky stalled the German advance, forcing them back to their start line. Had I had Naval support as an option when I entered that map, no question I wouldn't have been forced off it (I would have used it again next turn too), similar to what really happened. So there is no doubt history wise that it could be included in a few extra maps. I personally would just like to see it be available for all the beach maps, not just the landing maps.
I also think air power could have a more devastating effect in this game similar to Naval fire. Maybe insted of one plane, it would consist of several creating the same area of destruction that offshore does.
I can't say I'm entirely against expanding Naval Support to other maps provided the quantity of strikes is limited. It will just require a modification of tactics by the Germans. Keep moving, spread out or stay under cover, etc.
