I will not judge you, because each own have their own reasons to stay or leave any game. Myself, I always advise people to stop playing any game if the game is more frustrating than fun. That seems the case for you, so you have my support on this matter. I’ll keep the advise that if you miss OW in the future, you can still come back and play more casually. SR is just a number, and QP will always be the default game mode.
I have quit as well, and currently I only play when friends invite, but all my passion for the game is gone, and I’m here just for the lore and the forum drama.
I wish you have fun in the next game you jump in.
