Despite not doing it intentionally, I take great pleasure in spreading the healer disease in Alex 4. Usually if it's one extra person that gets it then no one else will, but whenever more than three people have it, it seems to spread faster than a STD at a rave for whatever reason.
More shameful, I've been so focused on DDing the second boss of Neverreap a few times that I don't bother curing or Esunaing the Bleeding status effect. I've had people die on me on the easiest boss in the game.
