| Ya those color symbols are cool, I think it's important to have action type and frequency somewhere predominant. Though, I would reconsider the standard action one, >> dosn't feel like a standard action, it seems more like a movement. And you might want to find something for full round actions (if there's such a thing in 4th ed).
Maybe have the frequency (at-will, encounter, daily) be a color somewhere or something, as long as it's the second most visible piece of info on the card, after action type (standard, move, minor). |
