Cause the caitlyn is a moron that probably wondered why her boots first, zeal item second build lost lane. Likely went on to blame the sona, who felt that spending an extra 800 gold for 15 magic pen was somehow worth it while negative k/d.
Meanwhile, fiora rushed the wrong item for the gnar matchup, despite having to purchase a component that could have been built into a better first item for the matchup, and started building ravenous hydra when significantly behind.
And veigar is tilted cause his team is marginally more retarded than he is, but he's still super retarded because he can't farm worth beans so he tries to compensate with k/d.
While amumu is crying permanently as he tries his hardest to do his job while his build is bad and his team is worse.
Welcome to bronze. Where everything is a lesson in futility, and games are lost rather than won.
