Fuel Burn 2.5X is a highly biased way of trying to enforce throttle controls as it would only do so for a subset of the aircraft in AH.
Thing is though, those very same short range fighters have no reason to throttle back. The only plane really effected if the throttle is not managed would be the ever popular La7 (La5, too). Remember, we're still talking 360 TAS and a 3000ft+ climb per minute (below 5000ft altitidue) when throttled back 4-5lbs on the manifold to gain back those 4-5 minutes lost with the 1/8th increase in fuel burn. Hardly a loss of anything. It would be the careless that would notice the effect.
I cant remember the last time I ran out of fuel in anything.
Fuel is NOT even an thought, it is NOT even a consideration unless the fighters are going on long range escort mission.
Fuel is an after thought. HTC can make some very small changes to make fuel just as important as ordnance, I've already outlined them in early posts. Even if HTC would not consider changing the burn rate, they could still change the penalty for destroyed fuel tanks on a field (max penalty at %50 fuel is my suggestion) and not allow DT's unless the plane is fully fueled.
MAKE fuel an issue, I implore HTC to at least consider testing the new fuel settings for a tour. If it adversely effects the game then switch it back.
