Kidding? A "solo" player is someone because of their preferences and tendencies. You're acting like if that "solo" player stands next to someone that everything about them just completely switches around and now they're a "team" player. Yeah, they got on a team. They aren't solo, at that moment. LFG is an outside alternative to matchmaking. Would you tear up someone's solo card as soon as they enter a matchmaking activity? Perhaps they have to keep rejoining pvp matches until they can find a 1v6...
