Thanks about manual. I've missed this thing. ok. will revise it)))
But this casting order is unchangeable!!!
And there is only one reason - some unit id!!!
When I plan the communion - it's deadly for some variants. and for order of spells and moving. I think that there is something wrong with ID's like reason for casting order.
I guess veto wanted to say that when action order is determined by some ID (which nothing at all in the game mechanics should me dependent by, IMO), it is much worse and inflexible than if it was determined by player. ID-based order will be perfect in this case as defalt one for those who don't like all that micro.
I think it's supposed to be conceptually a random order. The fact that we worked out that the "randomness" is actually just the unit ID just shows why you can never trust a pseudorandom number generator.
