1:1 maps are viable for SOME engagements: not all. What your proposing is we cut out alot of the freedom abilities for COs.
Let's use your Germany scenario for instance. The Axis already KNOW where they're coming from, with little ability. As the Allied CO, I can only move my bombers to enter into about 5 sectors, where if the whole continent was available, id have about 50. I could enter from Normandy, Calais, Holland, or Norway.
What it does is set up an easy massacre for the bombers. True, scenarios such as that are ALWAYS massacres, but at least the CO had some freedom on where to implant them.
It's really really hard to find battles that had suitable numbers. Hell, it was rare that more than 20-30 planes would hook up at once, except for the notable battles: Midway, Kursk, BoB...
Scenarios wouldnt be scenarios: They'd be bloody re-enactments. 'Today we're going to simulate the battle that 50 Zekes met 50 F6Fs over Guadalcanal. The objective is not to get shot down. Fight'
What your suggesting is more of a TOD. What you sound like you want is EXACTLY what the TOD does.
Scenarios are meant to be a chance to defy history, change the order of battle. If Rommel sent these 100 Stukas in first and got massacred, why do I want to do the same? I'm going to rewrite his plan, and WIN!
Scenarios are not and can never be reenactments, no way-no how. No one would ever fly for the losing side. Hell, we have enough trouble finding bomber pilots, and they KNOW theyre going to die. Scenarios have on objective: WIN. Win at all cost, defy history. Try to lead the Russians into victory over the Germans in Kursk 1. Lead the Germans into the obliteration of the RAF in BoB.
1:1 is viable for some scenarios, ones contained on a small area. Most however, require that we give the other side a shot to choose a different flight path. Otherwise, scenarios become predictable, and bland.
This is of course, all IMO.
