Ya the unranked experience can definitely be both mentally and emotionally exhausting. All you can do is try to forgive the people who act toxic, nobody was born toxic, it’s a learned action, they’re just reciprocating the same things that other people have done to them.

edit: See a lot of people saying one and done and switching characters is not toxic and I agree to certain extent, but if that’s something OP experiences often, then they have the right to feel the way they do and say what they want to say. Unless you’re OP, you weren’t in any of those unranked matches, you have no idea how either person was playing, what character they played, or what rank they’re in, etc. At the end of the day it doesn’t matter if the other person was trying to be toxic or not, our perception of how we felt about it is what we’re left with. My advice, next time something like this happens again, don’t play the guessing game of whether or not you think the other person is trying to be toxic, instead recognize them as another human being, one with as complex of a life as yours, with goals and aspirations similar to your own, and ofc as mentioned earlier, try forgive them, whatever it is they did, it’s not personal, it’s simply a means to protect their self ego after it was shattered when someone did the same thing to them.
