>>Hmm, that would be to make it completly useless in pk as you then would lag yourself 3-5 rounds.

I did not say that the lag on the spell should increase to more than 1 round. If you think about it, the spell would actually get some new uses in the hands of an intelligent mage.

Also, it would be far from useless to get away from pk. The number of situation where it's the preferrable method of escape would decrease slightly though.
