I have spent... 8281 devs on this skill, and I can still use it only slightly more than half the time, really. Some quick calculations and... this is a lot more expensive than any of the haste spells, even if you count the casting skill needed...

Is it just me, or is 8281 devs (Combat devs, too!) a bit on the high side? It's not like whirlwind is anything exceptional...

I'd suggest that whirlwind capped at 100%, and at 100% you could use it continously... It would still cost over 5,000 devs to get that high, don't worry. \:\)

Or possibly make it so higher whirlwind gave even more attacks... That would make it worth it too \:\)
