Yep. There are oodles of skills that are completely worthless because they don't need to be used in battle, ever and are a complete waste of stamina.

They need to:

1. Make those skills even remotely useful at all (Ambidexterity, Far Shot, Barbaric Yawp, Discerning Eye, etc)

2. Increase the length of time it stays active

3. Reduce the stamina cost

4. Reduce the AP cost
