I don't miss Umiron as an implementor. He was unreasonable on too many levels. Exactly because he didn't play mortals.

So him playing morts is doing both us and him a great deal of favor in my opinion. He NEEDS that experience if he ever decides to come back as an immortal (which I would prefer to happen later than sooner because the more mortal experience the better).

I also hope that he is heavily engaged in PK. Because laying your hands on PK without having vast experience of it is oh so painful for the playerbase.
