feel free to debate any points.
Free whirlwind is nuts, but keep in mind that Mithral Tornado effectively gives you a Standard-action Whirlwind attack. The SRD is a little tough on ya making it a Full-round action, I think, but it might have been too loose to allow it as a standard action every round.

The trade-off now seems to be a ranged full-round attack to all enemies one can hit, which should be better, no?
