Stop adding new meters, it's bad for newer players

Personally I think the laceration meter is unnecessary when there are mechanics in the game that can already provide a similar mechanic. I think using deep wounds would help make things more consistent for newer players and give this killer the buff I feel he needs. I would recommend requiring 2-4 knives to trigger deep wounds. The remaining knives could reduce deep wound timer.
