While we're on the subject of Domino, another thing that is not working crossed my mind.

The taunt icon is never shown.
Now for the smart ones thinking that maybe it's a hidden buff, it's not. And let me explain how I know this: Taunt works on All or Nothing nodes (can be tested by using a champion with the Taunt mechanic like Spark). I have tested her SP2 when the opponent is Unlucky several times in RTTL 4.3 (first node is an All or Nothing node), and it's impossible to bait a special. For a 70% chance, you would expect them to throw their specials pretty easily.
Hence disproving the notion that the Taunt ability is hidden, and proving that the ability is simply not working.
