i agree [@MonsieurShade] it all depends on how you use your character.
you listed things like Swords, Vehicles, Armor, Firearms, Crossbows and Shields. those would be good for hero support because you are assisting the hero with weapons. or you can make them yourself and be the hero.

for both my characters, Eve would be a hero, if it wasn't in her nature to do no violence, so she'll become support.
and Ava is Hero Support because her power is to assist more then action.
