Refusing to work with the rest of the team: reportable?
Been in my promos 3 times today, and each time the deciding loss came from a cc heavy support (Sona, Leona), who lategame decided they were effective split-pushers (they weren't). So while the entire enemy team is barreling down mid and crushing turrets, my team has no opportunity to counter-engage because the support is wave-clearing minions that are nowhere close to a turret top lane. Both times a clutch ult from the support would have given us the chance we need to take them out in a full teamfight and turn the game around for a win.
To sum this up, I feel that if a player is intentionally ignoring their teammates, especially if they are in a role or champ built around helping the team, can be considered a form of griefing and throwing. Would reports be justfied against these players in cases like this? In both cases they never communicated with the rest of the team through chat or pings or anything.
