How do you expect people to pay for Heroic Duels?

How do you expect duels to become more popular and people to want to pay to play heroic when cannibalism exists? On top of that Demon Hunter can still kill you on turn four and mana burn you out of one of those turns meaning you played 2 turns. You recently dropped a duels centered patch where I expected this stuff to be fixed but apparently you don’t really look at outcomes of duels games before adding new stuff to it. Atleast make Cannibalism tier 2 so you can’t have that and from the swamp, it’s literally pointless to build a deck at that point because you’re just playing through 2 treasures and winning every game. Cannibalism isn’t even fun to play with , it’s just a necessity if you want to get decent reward for your 2 dollars spent. From the swamp is insanely OP too but 1 step at a time I guess. There’s no risk reward to it like Double Time which doesn’t feel so bad losing to.
