I do dodges when my character really can't take the hit.

For example, Kino... really can't take hits. Not only is she canonically very good at not getting hit, but she's a tiny completely mundane teenaged girl. And I mean really tiny, she's shorter than every other non-child character in Kino's Journey. Unless I wanted to kill her, which I absolutely don't, she can't go taking hits. If she did she'd basically have to sit out the rest of the current challenge.

Kyouko can take more hits though.
