Activision Blizzard has been seriously mismanaged. They have very nice IP and a fanbase that is still somewhat loyal because of the glories of the past, but Microsoft would need to revitalize the management and the creativity.

- Overwatch hit the ground running to massive success, but hasn't materialized Overwatch 2 and has stagnated.

- Warcraft III Reforged is a total disaster and abandoned.

- WoW has a wide following of people in its vanilla form (i.e. taking things awy from what it has become), and the extensions aren't bringing a lot of value. There is speculation on whether it has hit its peak and is in decline.

- The Starcraft Remaster is basically the same game but with a bit nicer graphics.

- Diablo 3 seems to have done well.

I do hope it gets revitalized and the IP gets new life with better management, but Blizzard has been struggling.
