Unchained Action Economy
Unchained Action Economy as found here will be employed, but with some slight changes.
Use a Swift Ability: You use a single ability that can be used as a swift action.
Every round you get a free swift action, but if you want to use more than 1 swift action that turn they will have to be as simple actions. (ofcourse not multiple lay on hands, etc.).
With this swift action you can take a 5 foot step if you so desire, but that 5 foot will provoke aoo.
