Bold of you to assume that anyone has the time or effort to code a trigger lock for turret zoom, plus smooth out any and all bugs that would arise from it. Secondly, you're vastly underestimating people's ability to multitask. Ctrl is literally right under your keyboard hand, and scroll wheel is on your mouse. You'd require less than a second of flick to know exactly how your opponent is turning. You wouldn't need to turn your camera at all, given the range of turret zoom. If you're already turret steering, then that makes your job even easier, you wouldn't even need to change any keybinds. At that point, it would just be aiming your guns with zoom, then going back to an acceptable level to fire, then going back. It wouldn't even be difficult, it'd just require practice, like everything else to do with snub combat.
Though given the last 3 ideas of yours that I've found myself commenting on, I'd say you mostly play caps anyway. If you want establishing shots, get a camera ship. Snubs are actually just fine without turret zoom. The big issue is that you can't see the whole ship when you enter turret view, the bottom is always cut off. Any picture of the ship itself is ruined by this. The fix to it is not turret zoom, its changing the center of the turret view.
Funny meme directed at the funny meme man only gets you so much mercy. You are spared only for as long as it takes for me to finish a lengthy post about systems.
Right but seriously what you say, to me, is a perfect example of another boogy man scenario that is actually of neglegable impact in the end, and not worth it. When otherwise we enhance the quality of the game all around with something simple. Maybe since you have it all figured out, and everyone would have the same ability, you have less to worry about than you think. Too much has been held locked over the years because 'boogy men' scenario arguments. Its all in your head bro!
