The teams I'd been on did not have a tank, so that's what I would make. Nothing else was known going into the character creator, just "female tank". Shield Defense was just a month or so old, so I chose to go with something new. Since shields offered no self-heal, she went with Dark Melee, which has a self-healing attack.
I'm not sure why she ended up with the girly sailor look. I sort of liked the cat plushie on her shoulder, which led to her name. She was Kit, and it was Kat. Or maybe vice-versa. ;)
