You are right Loon, 25% fuel is too little, even with the 1.5 burn mult, as it pretty much makes the spitfires, typhoon, La-5/7 and tempest useless. You will get to the fight, make a pass, and rtb for fuel (unless the fight is over your base, in which case you're screwed anyway). It also limits the use of 190's and 109's, but not nearly as much as the rest I listed.
