HiTech for special events I don't see repositioning the now uncapturable strats as a problem. Simply because most special events actually have a player flying for 45 minutes to an hour to a target (250 miles or more one way). That is part of the event.
For the MA I would hazard that this might be an issue and would discourage bombing of strats. When we had the zone less system previously I believe it was on the smaller 256x256 maps, so designers could not place strats to far away from the initial battle fronts (before people started capturing bases).
On a 512x512 map you could easily end up with a situation with strats placed:
1) Strats being placed by the terrain designer to far away from the battle front resulting in an hour or more flight to the target and then another X amount time back to a friendly field. How many players in the MA do we know willing to fly an hour to get to a target and bomb it?
2) Strats being place to close to the front and being over runned and then being deep behind enemy lines. Resulting in the enemy country being able to hit them at will unopposed and degrade your countries supply while your country might have to fly say X amount minutes or more to fly to the strat target and defend it. Even if players do this they only have a certain amount of time over target defending it. Which again might produce the affect of the supply for one country simply being continually depressed with them not able to do anything about it. Say if strats were 100 miles to 125 miles (4 - 5 sectors behind enemy lines).
As stated I don't see this being an issue with special events (scenarios, FSO, snapshots, etc.) where people are used to and required to fly long distances. I do think this could be an issue in the various MAs.
