“Can I play [character?]”

Nothing more irritating than waiting in a DPS queue just to select a character and immediately hear the rustling of someone (probably a kid) hurriedly turning their mic on so they can ask you “please can I play [character]?” If you refuse to swap, you run the risk of them purposely throwing the match, but if you give them their character, they might be bad. It’s a tough choice to make, but if you don’t want to hear the whines of a pre-pubescent teen with a microphone who sounds like they’re parked next to a window AC unit, you might just wanna swap.
