What I mean is that when I turn my legs (necessary in a close-range fight), my crosshairs also instantly move in a way that's hard to compensate for with my mouse. As a result, I've found that my aim is only controllable and predictable when I'm moving in a straight line, with fine-grain adjustments being made only with the mouse, ideally before the reticle passes over the target during my straight forward or reverse movement (with no leg turning taking place).
I know I'm still very new to MWO right now, but I've been playing Mech games since Mechwarrior 2, so I understand that this type of thing would be a departure from past implementations of movement. I'm not trying to upset the establishment here, but I think this feature would be fun, and could add some more complexity to mech movement, while also making brawling a little smoother.
And if a player doesn't like it, they could just ignore it.

So anyways... bad idea? Interesting idea?
