The problem is this is a "Combat" game, NOT a "war" game. If it were a war game the impact of the strat damage would be important so increasing the effects would be ok. However this is a combat game, and anything that takes away the ability of doing combat isn't going to happen. You used to be able to take the fuel down to 25% at all airfields (you can only go down to 75% now). The reason it was changed was porkers would take the fuel down along a front and shutdown the ability to defend, killing the fight.
If you make the strats THAT important, and someone does take them out your hurting the ability to have combat. Again, a lot of people couldn't care less about "the war", they are here to have fun fighting in which ever venue that like, be it fighters, gv's, or sea battles. The objective these people is to beat the other guy, NOT win the war.
