Does Riot sends you a feedback if they punish someone that I reported? Idk what's going on but I've been seeing so much racist/sexist toxic players both in my team and opposite I reported 5 in the last 3 days but didn't receive any message...

As the title asks, why do some players switch between their melee weapons and their guns when it isn't necessary and if anything could be harmful to them because they'd have to play the equip animations?

Overwatch has a separate queue where Devs can experimentally balance heroes. I think experimental changes for agents or maps will be really fun to see and will keep the game fresh and exciting between patches.
