Not a fan of the killing guildmates either...idk seems cheap. I can definitely see why you do it though. I don't think people holding sards should be able to kill themselves on spikes though. I think bows/bombs could be disabled in towers and that could be a reasonable solution instead of 'last person to hit gets the kill' if this ever happened. I know some people will say this is part of strategy .etc, but I doubt it would change too much from happening/changing tower wise tbh.
