Walk up to Classick's machine to see an open ticket;
"fix morde's overnerfs huehuehuehuehue"
I lol'd. And yes, we're doing some work on Morde's balance.
Also, I don't know if you're actually following up reading posts but I had a cool group of suggestions about morde a while back
Primarily dealing with the cost of his spells and his shield. Mainly suggesting that his spell casts scale higher but start lower, or that his shield deteriorates into a % of it as HP over time.
Edit again: At under post. Morde's only weakness was that he has no CC. It's what makes him Morde.
