Muzzleflashes unrealistic?

"If they manage to create a muzzle flash that is random and has a fair amount of alpha channel in it they're gonna nail it."

Yes, that's right, this will be a good solution, but again, it depends on so many factors, that a single rule will be hard to find.

But remember one thing, weapons engineers are not retards, they would not conceive for instance a nose gun with a heavy muzzleflash which would empeach the pilot to see anything when firing, it's simply not logical.
