First, I would suggest be turned into a toggle button, rather that a press and hold, since quite frankly it's trivial for folks with better equipment to just make a programmable toggle script anyway.
Second, I propose that the current arm lock functionality be changed such that when you lock the mech's arms if that mech has lower arm actuators, that it raise its arms and lock the ELBOWS of the mech.
What this would do, is that it would remove what is often a penalty for mechs with lower arm actuators. So, mechs like the Atlas would then be able to raise its arms up and fire over ridges.
Currently, mechs with lower arm actuators, in many cases, are basically penalized. The are forced to spend extra critical space on those actuators, and cannot choose to remove them. Also, having lower arm actuators ends up putting guns much lower on a mech's profile, which tends to be disadvantageous in a game like MWO.
In theory, lower arm actuators are supposed to have NO downside, other than the critical slots they take up. For this reason, I'd suggest making the aforementioned change, as it would tend to give pilots another piloting option, while removing a penalty on certain mechs which really shouldn't be a penalty at all.
