Pinhead should not break his own chains

It is artificially punishing and anti-skill. Regardless of where the player chains the survivor from, where the others will spawn is more or less random, and it can put you in lose-lose situations:

Option A: You detour around the chains, losing the time the chains would have bought, nullifying the point of the power.

Option B: You walk through the chains, instantly destroying them, nullifying the point of the power.
