We've got a lot of options at our disposal that we haven't tried yet. Which is pretty ridiculous, to me. I've read about there being...blood replenishing potions in the infirmary, and there may be the option of making more. There are people who can't die on board - so why isn't their blood being made use of? The vamps that are attacking need to be dealt with, but that doesn't mean they should all be punished.
