I have a Company leader driving a Banshee 3E. He puts it to good use getting into the thick of it, and two 10 point punches make him a habitual head-capper. I would like to get the AC-5 replaced with an AC-10, or something with more power, but I'm not complaining.
IMHO, you look at how the 'mech is built, and play to its strengths, obviously. YMMV.
