I see what he's getting at. He wants to see some results from hitting individual hangars, and not just when hitting all of the hangars (of the same type.)
This one isn't too bad of an idea. Why? It's not much different from taking out the FH altogether.
MX, the reason you want to limit fighters upping from a field is to take the field. That's what happens when you take out ALL the fighter hangars at a field. No fighters at all can up from it. All Pepe is suggesting is extending it so that taking out some of the hangars has an immediate effect.
SW, in a way you argued for Pepe. You're right, taking down hangars in real life had little effect, they weren't the targets. You're also right in that we're using the hangars instead, since this is a simulation game. IRL, if you took out 25% of the planes parked on a field, that's 25% that immediately couldn't come up. If you took out 100%, 100% couldn't come up. With the current AH setup, taking 25% of the FH out does nothing immediately. Taking out 100% of the FH does have an immediate impact.
The general concept behind the idea is a good one. The proposed implementation, I'm not too sure about.
