I feel like telling people to just "Carry yourself" out of bronze/silver is leading to bad teams:

Surely with this much OP broke cheese freelo a team can win right? Well not really, as I've become painfully aware people don't understand team fight dynamics, champion roles, or really anything about this game other then "there are three lanes, I'm suppose to last hit minions, ADC goes bot." Instead folks down here assume "Hey I need to carry, everyone else is terrible, so I'm going to take my carry champion," so what you end up with is 4 carries and a squishy support who either snowball off, or simply fail. Even when they snowball off they probably won't group and trying to 1v4 the enemy team until they piddle away any advantage they had.
So I'm just going to say, tanks and front-lines win games. Not carries. And for the love of god if your adc is fed protect them!
