I was also wondering, why fix somefink which was working. Playing BB demo i constantly find my left hand fingers pressing Shift key, when i want to strafe sideways, it's almost like second nature to me. Also, i miss the ability to place cursor in the bottom corners and rotate and move backwards simultaniosly.
And the good ol' Tab/1 is also made worse IMO, i mean, i like backsides (of tanks in this case ), but not when given rear obscures the view of battlefield.
