According to Hearthstone Mathematics youtube chanel, the constructed game mode in HS is losing interested big time.
With the recent success of Yu-Gi-Oh Master Duel...that followed on Legends of Runeterra trend to make the game more Free to Play friendly...
Do you think (like i do) this 2 games mark the start of a new generation of online card games which is much more F2P friendly than Blizzard's itteration?
That may result in HS's downfall? Maybe?
