Trouble is, how do we know if a object is coming into blender with proper scale,I mean how do we adjust for the differences between what ue4 says about ‘scale and rotation and location’, and know what we see in blender is as it should be ? 
That would go a long was to ending some frustration Im sure many have.
Oh btw I tried 2.73,but its not very stable atm, as it lags horribly on the same mesh where 2.72b doesn’t but of course its a RC so no huge surprises probably.
