I completely agree with you! Blizzard is a long time Mac developer. I don’t buy PC/Mac for gaming, but it’s a nice bonus to have such a competent developer aboard.
I was very disappointed when Overwatch didn’t come to Mac, but that was also a time of transition from OpenGl to Metal, but that excuse became less relevant, especially because Blizzard has mastered Metal in WoW, SC2 etc.
But this is a mighty blow! I would prefer if Blizzard could just be honest with us, and tell us if they have abandoned Mac development, instead of keeping us in the unknown.
The only reason for blizzard to not develop for MacOS or Linux would be because they don’t find it profitable.
Everything els is a lousy excuse.
