From my point of view I plan that into my flight path. I'll take a longer route to the fight to burn off more gas if I think Im going to need to be lower fuel state. In many cases you'll see me fight with a drop still hanging from my P47 because I know Ill need the fuel to linger. To me its all part of the game. Manage your fuel, manage your ammo, manage your E state.
I think that might be one of the things lost to todays players. They would rather look for added game mechanics instead of "thinking" about all that other crap. Why think about maneuvering for position when you can HO and get an easy kill/up a new plane.
To me, its part of the strategy. Load out the right amount of fuel, ammo, bombs,rockets to complete the mission you have in mind. Do any of the newer players have a mission in mind or do they just launch with the horde? The game is so much more IF you use what they put into it.
