In solo QM, the game will force 50% WR on you extremely hard. you will not get more than ~55% unless you're at the very top of the player bracket. These kind of WR (picrel) is not really possible anymore. (I had like 66% WR on pre-rework Samuro. he was broken as fuck)

In Ranked, you will be above 50% when you're climbing and you will probably stay a bit above 50% when you're at your place. so there's not much to say
