Give us one or two of these for each country on an MA map. Tie in the strat so that THIS is the thing that you have to take down at least 75% in order to slow refresh times.
I'm saying get rid of the 1-tile "factories" that have no realism being set in the middle of 8K box canyons, or in deserts 100mi from anything.
Give us this, and at least we can have FUN bombing stuff in the MA. Bombers get more to bomb, they also know what they are bombing is helping, but that they ALONE cannot take something out. Due to the sheer size it would take concentrated efforts by any one country to take down the strat of another, but dangit if it wouldn't be a blast to try!
Bombers get to enjoy their aspects of the game, fighters get to escort, or intercept them, and GVs get the fun of trying to drive through these things shooting buildings or other GVs.
Why is this in the wishlist? It's just custom tile items, you say? That's true. However, HTC won't accept MA maps with custom object tiles. Give us the CT bombing strat in our everyday MA and I'll for sure be bombing a lot more.
It's just not so fun bombing a 1-tile square.
As for the practicality, make down times the same, or divide the "object" (aka the city) into grids so different parts affect resupply of troops, dar, ack, etc.
