Breaking out of pins is ridiculously difficult, and needs a tweak.

Pinning as a vampire is realistically the only way to safely get your first kill. The 30 second stun isnt long enough to drain someone, and they can sometimes even get a radio message out. By pinning them you can remove their headset and they wont be able to stand up and run away. It isnt hard to avoid getting pinned, and it isnt hard to break a pin.

There's this thing called "strangulation".
