I have had this "problem" for  while now, I have asked about it, Rowan tried to figure it out and then said he will inform admins. I am not sure if the message got passed on, so I am posting it here now.
Whenever I use ender pearl, I don't get damaged. Anytime, anywhere, wearing anything. Tried long throws, short throws, while hungry,  no matter what, I don't take damage form using ender pearls. I have tried to limit myself, so that I don't have an unfair advantage, but it;s difficult to not use them at all. Any advice?
