Question regarding Hanks Shield mastery


So I’ve had plenty of matches with Hank and shielded a LOT of team mates from damage, especially against Flamebreath and Supernova but my 2 Star mastery doesn’t get up at all? Both in the mastery progression as in the game resume, it shows I’ve done zero shielding from damage? Do I need to do something differently or is this a bug?


I think it is a bug. I shielded bots from damage a lot. I now have Bucket.


that how I got him
