Seriously - it's time we gave the models some actual character, some personality...
Seriously. I've been chewing on this for awhile, and my idea for decent models would be the following:
Gunner: Large (but too damn large) black chick w/ a New York -ish attitude. She's a slow-mover anyway, so there may as well be a reason for it :)
Sniper: Smart-assed hillbilly; sort of like a trailer-park version of Sgt. York.
Recon: Skinny flying 18-yr-old chick with an Uzi... semi-Goth but not too much so.
Arsonist: Redheaded, barely-dressed and PMS-laden wench, with a flame-thrower... to replace nurse as resident babe.
Nurse: Umm, "medic" would prolly be a better term... make him a guy and kinda geeky - not too sure about this one yet, though.
Marine: not much needed to change there. Same with -
Cyborg: Though I'd like to fire up something better than all-metal or all human - a true cross between the two.
Merc (hah! had you going for a minute, didn't I?)
Drop yer ideas here for the rest...
