How do i get into DRG?

I've been wanting to play this for a while now but i just never knew how to get into it, and i don't have any friends that i can play with so i'd have to play with randoms, which leads me to my next question, are people toxic in this game? I'll inevitably be bad at the game but will people just start ragging on me for being bad?

I want to Rock and Stone for Karl as soon as possible so an answer would be appreciated
