I still think Rat King's Ult is too strong

I really don't like the fact that there isn't much in the way of being able to win an objective when he has his ult up. Good Rat Kings will wedge themselves so that the buff stays up for not just the slam time but for the entire run time as well. I just don't think Ults with basically no counterplay other than "run away" is fun to go against. I know people will point to his win rate going down but just because he isn't a free win doesn't mean his ult is fun or fair to play against.
