I remember Old Urgot.
If I have anything to say about him is that gameplay-wise, he was pretty unique. While I can understand why his [E]+[W] combo had to be removed, it was his Ultimate that always stood out for me.
His Ultimate was just one of those abilities that could either swing a teamfight in your teams favor or Charlie Brown the user (Putting yourself in the middle of the enemy team with no backup). You could say that Urgot can still do this since he can still displace you with his [E: Disdain] & his [R: Fear Beyond Death] still carries an AoE Fear, but it doesn't feel the same.
Balance-wise, the version we have is alot easier for the Balance team to work around. Pumping in & taking away numbers wouldn't fix anything. Imagine if they pulled that with Old Yorick, pretty sure people would be upset if he had numbers pumped into him.
