A bigger problem is that it completely destroys the use of a tactical reserve. And it throws the unit balance off since certain units have higher stamina for a reason (ex. Peltasts).

I suppose it is one way to give the A.I an edge, though I prefer either /H, or limiting army strength/compositions.

Btw with the Darth mod the A.I doesn't waste as much energy in pointless maneuvers. If you go towards them immediately they will form up and fight with about the same energy.
