Maybe it is, assuming there's actually a good basis for making supposed absolute comparisons of scale when the games aren't explicit about relative values.

But these systems don't exist in isolation. Regardless of what it is by itself, Halo 4's movement seems to function too slow for its gunplay. Maybe making shooting more difficult by heavily decreasing aim assist on everything would also work. I'd be all for that as an alternative. Or implementing projectiles rather than hitscan. Whatever.

The point is, they're changing one of these values in a manner that seems sensible relative to the other values.
