update created two new problem s

@EA_Mako  I have investigated and determined the problem is partly mine, but also partly ME3 (as opposed to ME1 and 2). 

My controller may not be perfect, so my left analogue stick’s range when pointed up is ever so slightly limited compared to other directions. Think of it as the opposite of a deadzone, this is the maximum reach and sensitivity of the stick towards the outer edges. I noticed this when I found I could sprint (left stick + holding A button) while turning left or right (diagonal directions) but not when just sprinting forward in a straight line. I used software to measure my controller and verified. 

however, this is not a problem in ME1 and ME2 because the threshold it has to register things like sprinting seems to be lower than ME3. I.e. there is a minimum amount that your left stick has to be pointed up before pressing A button will initiate sprinting- point a little up and shepard will just walk forward, but point all the way up and it will start sprinting. So the problem is my left stick seems to reach far enough to satisfy the threshold for ME1 and 2, but not far enough in ME3. So EA could potentially re-consider those zones and thresholds for ME3, to bring it down to ME1 and ME2’s levels.
