but but Ill be popular with the ladies when I rescue them with Gerwalk and all of them will fall in love with me. Its quite 'USEFUL' for the guys.
Seriously though Gerwalk is the "Jack of all trades" between Fighter and Battroid. You get some advantages of both modes in one. You are quite right in terms of fear factor of the Battroids, but only works for small rebels, early civil war days. Against a seriously equipped enemy (Human/Zentran/Vajra/Protodevln) it doesnt mean much.
