Make his W remove all forms of CC and give him 10/20/30/40/50% tenacity for the duration and remove the snare removal from his Q (keep the move speed). Also up the base damage of his spin. Remove some AD scaling if you want, but up the base.
His W would be a "I'm a tank rararara" button.
I feel like his W is useless a lot of the time...
Think we might ever get changes like that? D:
