I was kinda ignored, so I'll just say things again.
This really is in the case of unupped, less so upgraded, but:
The best single targeting CC in my opinion is lightning.
Not many things survive lightning- If we did every creature in the game, over half would die to lightning.
That costs half of this, and doesn't hurt you.
If you had the choice, why on earth would you ever use the unupped Waive?
In terms of the upgraded Abdicate, that's a different story.
