Hi,
Yes it should, but I don't think it should be shipped with the official set of actions, since if you study carefully, they are very very generic and not tight to a particular kind of use ( games, architecture, simulation, what ever).
Indeed, one could create such set of custom actions acting like a framework to build FPS shooter quickly with fsm, and sell it on the unity asset store! that would be really cool!
The "problem" with this, is that it needs proper vision and funding OR some addict to build such set of actions. Not everyone build games with Unity and not all games have enemies you shoot at, so really the target audience is narrow in some extend and would be difficult to justify an official set ( altho it would be welcome of course, because would demonstrate the true power of playmaker versatility).
Bye,
Jean
