After feeling peer pressure from a tweet by eXtine, I took the plunge and reinstalled Starcraft 2. The last time I played was prior to the great redesign, i.e. the removal of the mothership core. The game at the time was just too frustrating for me and too random to justify playing, and the disappointing ending to Nova Covert Ops was the straw that broke the camel's back. The fact that none of my friends played discouraged me even more.
What resources are there now for getting back into the game? I know about Spawning Tool but I've never been able to get the Overwolf overlay to work properly.
Back in the day, I could go into the Strategy Forums or to Liquipedia to get a crash course on current meta builds, but these avenues are very dead compared to when I first started posting here.
Any videos, sites (other than TL.net), and other stuff to read/watch/listen to in order to get back up to speed on Starcraft 2?
FWIW I was Diamond 3 when I quit in 2016. I used to be Diamond Random before they added league tiers. I want to play Random again for the bragging rights.
