I have never been too much into the whole "Totem 'Mechs" thing. I can accept that designers slightly altered the appearance of a 'Mech to resemble its namesake - those little "ears" on Panther's and Wolfhound's heads, for example. Okay, that's a cosmetical harmless detail.
But when the form goes into the way of the function (such as in case of Fire Scorpion), I think this is wrong.
