Depending on what you’re using, but on PC if you go to the menu bars by your username there’s an option to filter your feed by different categories including subscribed.
I agree though, would be better to have that in a more noticeable place eventually because it’s not super intuitive.
I spent most of my 200+ hours in DRG so far playing with randoms because my friends aren’t as into it as I am. I can definitely say random matchmaking works great, and the community is amazing barring a few leaf lovers here and there.
Also the DLC is all cosmetic, so no need to buy any if you don’t want.
