spell priority???

ok...I notice the computer AI uses some spells more sparingly than others...such as a priest will cast heal or a dreadlord will cast sleep way more often and quicker than a druid of the claw casting rejuvinate or a creep casting monsoon.

I know you can change the position of a unit in a formation....so is there anyway to prioritize a spell making the AI use it more often...or be more choosey with it. And don't know a lick of scripting or jass...so an answer with just using the editor will be nice

unfortunately the only priority when it comes to spell modding is the dumb spell steal priority. which, if in range of defensive spells, its gonna take the spell anyway. plus triggers dont leave you with many options when it comes to spell's casted in a certain order, or at least the way you want it.
