Improve your last hits, if you don't have 100 cs by 10 minutes you won't climb out of bronze
You don't need 100 cs by 10 to climb out of bronze, but it helps a lot.
Play viable champions, not trash like mordekaiser, ashe, and urgot.
Ashe is good in bronze because she's one of the few ADCs that let you start a team fight, counter engage, and brings CC to the table so you aren't completely useless when you fall behind.
Also, any champ will work, but those with a high barrier to entry are a mistake.
Don't play support, you can't climb out of bronze or silver with support no matter what people might say.
This is BS.
Ward, ward, ward. Early game, middle game, late game. 10% of your playtime time should be dedicated to warding.
This is okay, but warding is useless if you don't learn to keep checking the map first.
Do your best not to die
This is a good idea at any elo
Consider getting a boot of mobility.
Meh. Some champs work with mobis, others not so much.
