AI for a non melee map?

From what I've read, there doesn't seem to be a way to use AI for a map that is not a melee map with many custom settings.

Am I wrong here? I have a map in which I need to absolutely control the positioning of buildings by the computer. Would it be stupid to try to write an AI for this rather than just using some advanced triggering with JASS?

Since you would end up doing similar stuff in the AI script as in the trigger solution I'd suggest the trigger since you will probably not have that much use for the special stuff AI scripts provide.
