Sword damage seems lower than ever. I hit a player 14 times and he did not die. Video evidence: https://www.youtube.com/watch?v=_hVVx9FUdfg&feature=youtu.be
It also takes 4+ hits to kill a zombie.
Swords are weapons designed for one purpose, killing. They should be higher damage, especially because they lack other functionality (can't cut kindling/chop wood).
