You can always carry harder/Gold as a predictor of games
I just had one of those rare matches where team gold did not predict the game outcome. We won with the other team ahead by 8.1k.
While it's very rare for gold not to predict the outcome of the games it does happen. This was a Bronze IV/V match clearly the other team didn't know how to finish.
This match is also proof to all those stuck in Bronze that you can carry your team, no matter how bad they are. Take a look at the match if you think Elo Hell exists.
