Hi,
Actually, I don't think it's totally the idea to wipe out scripting, Each actions is scripted. What playmaker gives you is the power to work with events and states, but each actions remains standard script, totally open for you do create new actions, doing all the crazy things you want. no limitation there ( and if there is... make sure you mention it in this forum).
as for array, give arrayMaker a go, it might offer you a good starting point for working with array within playmaker.

http://hutonggames.com/playmakerforum/index.php?topic=1088.msg4553;topicseen#msg4553If you are ok with scripting, you will likely find the right balance between scripting outside playmaker and actually create the actions you need to stay within playmaker environment. Personnally, I very much enjoy creating actions to still benefit from the HUGE benefit of working with events and states. For some process like inverse kinematics and highly mathematical/trigonometric stuff involving numerous variables and complex equations, yes scripting has the edge over playmaker in terms of clarity.
Bye,
