FYI: I encourage people to NOT use zoom on aircraft and just see how well you hit. I've found that I'm actually more accurate when I do not zoom in, at least not zoomed all the way it. It is easier, or at least I perceive it to be easier to judge all the variables of the enemy plane when I'm not zoomed in all the way. This is especially even more true when attacking bombers.
I don't always go by the "if it isn't broke don't fix it" maxim. Sometimes, I think people forget that everything outside of the "hard" data is completely arbitrary. Meaning things that are not hard wired to rate of fire, airspeed, climb rates, turn rates, etc, are %100 pulled out of the air by HTC. Did pilots in WWII have the capability to zoom in??? Obviously not. There is a trade off most certainly, the players need to be able to play the game. I sometimes wish that HTC would adjust things like pilot and TC zoom view abilities from time to time. Same goes for the rate of fire for tanks, G force threshold for black outs (not all pilots blacked out at the same G force), and other "soft" data.
