I'm half-tempted to use the revised
"Unchained Action Economy" from the Pathfinder Unchained book. It's a much less clunky system.
A quote describing it:
OOC:
The default action economy is intricate—full of exceptions, nonactions, and strange actions. This revised action economy streamlines the process of combat encounters. In many ways, it's a more active system that allows lower-level characters more options in a round while slightly limiting how much higher-level characters can do during their turns.
In this system, a character can commit up to 3 acts on her turn; these can be committed individually as simple actions, or combined into advanced actions. When it's not her turn, a character can take a single reaction per round. Iterative attacks have been discarded in this action economy. Instead, any character can make multiple attacks during her turn simply by taking multiple actions to do so.
It's pretty simple, more balanced, and fixes one of my main problems with PF: Low level characters have too few options in a round while high-level characters have too many.
