ELO HELL IS LIKE THE PRISON IN THE DARK KNIGHT RISES. THERE IS A ROPE CLIMB, A CLIMB UP A STONE WALL STRAIGHT UP A JUMP THAT ONLY A 12 YR OLD GYMNASTIC GIRL CAN MAKE ALL WITH A BROKEN BACK.
GOOD NEWS IS ONCE YOU MAKE THAT CLIMB AND GET OUT YOU STILL HAVE TO DISABLE A NUCLEAR BOMB AND FACE THE ENEMY THAT ORIGINALLY BROKE YOUR BACK.
ONCE YOU DO ALL THAT YOU CAN VAST IN THE GLORY OF ELO SIMILAR TO VACATIONING IN THE FRENCH RIVERA.
the best thing you can do til you are able to dedicate more time to the game ( thank your parents for allowing you to live on league) is improve at fundamentals of the game. such as last hitting, wave control, map control , warding, objectives. if you stop worrying about winning and focus on those with simple mechanical champs by default you will climb. at 1st you will lose when you focus on those objectives. but in the long run that will make you a better player and being a better player will help you climb out of bronze. there is so much to this game, its alot more then being able to 1 vs 1 your enemy. its damage foresight , knowing match ups, cooldowns, when you can push advantages, when you cant. how not to feed. how to get feed. how to position correctly.
now if you just want to climb and gain elo you can learn the new champs each month spam those til they are nerfed or other champs buffed to counter them and abuse that. but that wont directly have the long term improvement as the fundamentals.
