If you're struggling in low elo, I highly recommend picking up Master Yi
While some of you might not like playing the jungle role, let me tell you that Master Yi is insanely broken especially at low elo, and you really need to pick him up. He clears camps relatively well, he clears objectives very well now that dragon has lower health, and he scales like a madman into the lategame. AND he's easy to play. Like what else do you need? I've been having lots of success on him because once you get a few items it's pretty much game over for the enemy team if you're behind or ahead. While he does require a half decent team to carry, he can solo carry teamfights in a way that not a lot of champions can due to his tank shredding potential plus his absurd healing. Seriously my low elo brothers and sisters you need to learn this champion before he gets nerfed, even if you're not a fan of jungling, because the reward is huge when you know what you're doing.
