I just have a desktop pc and a laptop and want to play games like overwatch at home and on the go because I don't have an account lock or something like that, I ask
That's fine.
Yes, of course it works. As far as I know, you just can't log in to multiple devices with the same account.
You can also install it on 1000 devices and link it to your account if you enjoy it. Blizzard doesn't mind that.
You can't wear the game on both PCs at the same time.
Otherwise no problem
Thanks for the answer
That's clear but thanks
OK thanks
