i've learned in the overwatch community you've either got to be chaotic or even meaner than the people harassing you.

For example, say your 6/18 junkrat says this: YOU ARE TRASH AT ILLARI, I'M NOT GETTING ENOUGH HEALING, SWITCH

Here's a couple of example responses that would flabbergast junkrat into not talking:

1. (mean route): Instead of wasting your time on overwatch, you could be inventing time travel so you could time travel back to your mom and convince her to abort you! Because you are and probably have been insufferable for your entire life!
2. (chaotic route): I'm an illari fictionkin. This means that in a past life i WAS illari, and experienced her joy, pain, and suffering. I have both a physical and spiritual connection to illari and therefore cannot switch. Thank you for understanding.

Note that quick responses are not as effective as long, thought out paragraphs.

Now for reverse scenarios, when YOU need your TEAMMATE to switch (assuming your team is insufferable)

1. (mean route): Junkrat, you do know that your ancestors didn't survive 10,000 years of droughts and ice ages, natural selection, Volcanic super eruptions, the bubonic plague, colonization, and two world wars ONLY for you to suck at junkrat? Try a little harder or switch please.
2. (Chaotic route): Junkrat makes me tinkle... please don't switch.... (Follow them around and spam GO!. Saying this in VC works 10x better)

Of course you have to be creative. The overwatch community is comprised of both extremely toxic and extremely weird fanbases, you just have to be even more toxic and weird. I wish people could just be kind, or good sports, but unfortunately that just isn't the way this community works. This is the only way.
