I think it's good that they're going to do it :)
Would be a nice update. You can already play Warcraft Rumble on M series Macs.Though they never made Diablo Immortal available on Macs for some reason.
Runs terribly and has way too many loading screens for a game that plays in such quick bursts, I would love it it's brought to PC!
That's a good news.
I'd at least give it a try if it was on PC. I really don't like playing games on mobile simply because it's too small for me.
I for one hate playing on my phone and Tablet unless I absolutely have to, like when at appointments in the waiting room or something. I would rather play WoW Rumble on my PC as that is what I always play on when at home and I play 90% of the time at home. So I 100% hope they bring it to PC as I would play it more often if it was on PC.
