In what standard maps for Single-player Adventure is resurrection not useful?
"In simple terms"...
You have one type of gameplay: "run - kill neutrals - win." This is a ready-made solution that you want to apply to win.
I believe that the game should provide the player with options; he should come up with what needs to be done to win.
That is, for example, the option: "run - kill neutrals - lose troops... but the experience gained is less than the troops the opponent saved" - you don't even consider it.
Of course, the Single-player Adventure "on resurrection" will be strong, but it will create a linear game with one way to play (a monotonous tactic).
