Blizzard need do something about team 5 before it to late because not make enough money seem if bots fill game and raise their prices. So they need fire them bring on new design team when they switch over Microsoft. The CEO going so should the teams to because lose money on tiles if sell the company.
Hearthstone push to much card generation , manna cheat , power-creep now. Hearthstone going out like yugioh did.
MS changes since they took over already been stuff like firing most of customer support.
I would not advocate for MS taking a more active role in game managment, considering their infamous reputation of having a game graveyard.
Magic the gather take any other card game on the market and be here long after hearthstone gone. It strongest running card game paired to all the rest.
