Well, it's supposed to be more of a LOTR game than a hardcore RTS game. You don't always have total control of a unit... Example: You have a Mumakil on a rampage... it gets shot a LOT... it runs all over and you lose control because it's hurt. Ex. #2: You have an Ent kicking butt... someone sets it on fire... it runs for water on it's own.
