We should remember that there's a massive horde of these things that are constantly attacking people.  Being able to see everything that's happening, or rushing to a single person's aid isn't probable, and even if a character saw someone in need of help they'd have to cut their way through intervening monsters to get there.  Unless the character's special power gives the character omniscience or clairvoyance the amount of characters you can run and save should be limited, and being able to show up at the nick of time shouldn't happen often, if ever.<br/><br/>At least until we get more training and organization.
