That combined with the fact they've lost a significant amount of what constituted their top senior creative talent I'm going to say two things:
First they're probably a sound investment, they'll probably keep climbing as the MTX proliferates and as things like Diablo 4 on the horizon release and Warzone through Activision is still massively popular as ever.
And second they're probably not a place where you can expect massive innovation and polish in games any longer, and if you were a fan, like myself, that magical time is over, maybe look to Dreamhaven that some of that senior creative talent founded and others have gone to since leaving.
