Bronze has too many trolls to carry in.
As a Diamond level player, it is not possible to carry Bronze players. The elo is filled with WAY too many trolls and toxic players. 9/10 games you are forced to play 3v5 and even then the other 2 players on your team are really bad at the game and don't listen. If you are in Bronze, you will never get out no matter how good you are, unless you happen to get lucky and get a lucky win streak somehow. The elo relies way too much on luck, due to the large majority of players being overly toxic and trolling games. You can down vote this all you want but its the truth and everyone knows it. The math doesn't lie.
