i played OW for 2 years. inting is usually caused by very negative team atmosphere.
so if you want to do something about it you can start by inspiring others to be better by leading by example. which, honestly, looking at this game's community.... is too big a task to ask. in all the time i played OW i have never met a group of players I have wanted to help win less than I want to help people in LoL win.
Legit the most toxic community I have ever had the displeasure of interacting with. Actually almost got into LoL, really dodged a bullet on that one having a teamchat full of "refund skin riven ur trash" within all 1 hours of playing this game lol. Refused to take the abuse from these people and I'm the one who got punished for it LOL.
