I never played on the Battle.net. I always played against the machine. 
I was introduced to it by my kids. 
They also introduced me to a game called Diablo and Diablo II.
They were real time suckers.

Oh bring me back to the days of dial up StarCraft Battle.net with my friend and taking up the LAN line to the house for hours until I got yelled at 🙏

I never did this one either, but I played StarCraft (I believe that was the name) made by Blizzard, too. It was building and fighting.
