non-benders are badass you lesbians, true men don't use little pansy elements to fight.
i'm also pretty sure in one of the episodes there was some kind of fire resistant suit or sheild or something. your also pretty much the only one with some kind of weapon, so if a bender gets tired (i'm sure bending is just a tiring as manly fighting) all they can do is slap their little pansy hands at you until you CUT THEM OFF WITH YOUR MAN SWORD.
Although fighting earth benders would suck because they could just destroy the ground under you.
