Duels Lucia has more than 50 health and counting

Played a heroic Duels game against Lucia where the opponent had more than 50 health (and counting) and is messing around with me. Please fix this.

I got a screenshot and have copied it to my clipboard but have no idea how to paste it here. Why must you make things so difficult, Bliz? And PLEASE, get rid of these damn CHEATERS who are ruining the game!
