AI and important enchantments.

I was building support elem when during testing I've realized that hero won't maintain Master of Magic... O_o Just because. When combat begins my clever hero casts: MoM and Aria of Zeal losing 4,5 sec and does it every single time even though he was on full energy. So my question is: Is there any way to order them to maintain some skills or get some "cast all" macro. I do know and use "Order hero 1 use skill 1" keys but that's only for 3 heroes...

Well.. no, heroes are generally bad at it, unless you use autohotkey or similar to force trigger MoM every 45-60 second.

yup, they'll try and keep all enchantments up all the time. But honestly unless you are playing end of game hom stuff it is not that big a deal.
