I always thought Hyosho was very clever it used Kasatsu to enable the usage of a very underused button combination of Hyoton. I think we should look at using some very underused buttons for our upgraded skills button presses.

I think the throwing gcds are a great choice. Making enhanced version of a flashy looking piercing talon or Tomahawk would be great use of an otherwise pretty neglected button once a minute or maybe once every two minutes.
