The toxicity is awful. I tried to learn once since I had a buddy that loved the game and I was looking for a game to dump some hours in. This was about 10 years ago or so. My buddy told me he would help teach me the game so I could at least understand what people were saying. It took him one game to start trashing my playing. I fucked off of that game and never played again.
I do not understand how anyone continues to stay in a toxic fanbase even if they really love the game.
