solar, I don't think that this will happen simply because a creature only sees forward and turning costs a game turn. If a creature saw its attacker and tried to run away, that means that it would have to turn and then begin moving. Plus it would never know whether the attacker is still follwing it (as it doesn't have eyes on the back of its head). And it is bound to run into a wall as well.
We'll see with the first round of the competition whether the rules are OK or not and what should be changed.
