He can play whoever the hell he wants wherever the hell he wants quit being a shit-stain and politely ask him to switch for the sake of comp instead of whining like a fucking child
God I'm so tired of listening to people like you bitch on VC about this shit
You people fail to realize that quick play and comp are two different styles of play. While someone could be a god genji in quick play they could be trash at genji in comp for that very reason.
Practicing a character you want to play in comp can only be done IN COMP
