hm no.
Bronze- people with bad internet, knowledge, mechanics, also the majority are people who play while drunk, high, or lagging.
Silver- People have better mechanics, but lack runes, advnced knowledge, and still have net issues, higher rate of toxicity.
Gold- everyone has basic mechanics, most have general knowledge of game, and games tend to be more skillful, but you still will have trolls.
Plat and up- People in these Elo's are what truly end up making the game feel competitive, only downside is you get flamed hard for anything that isnt "meta"
Judging from your post, you seem to be Bronze/silver. your probably prone to raging/tilt whe teammates do badly and that causes you to do worse. I recommend learning how to effectivly split push, if your retard team can keep the enemy team at mid and you have a zzrot that pushes the waves to the top turret or bot, you can get 2+ turrets each time.
also as a Yi, you dont want to focus on being 1/0, you want to focus on your stacks. Yi's strength is not his ganks, its his lategame pushing potential.
Sated Devourer- Guinsos Rageblade- Bork/Black Cleaver/Titanic hydra- SpiritVisage/Deadmans-Steraks Gauge
Get bork if they have Supertanks (Voli, Sion, Mundo, Garen, etc), Black cleaver if they all have a bunch of armor, Titanic hydra if they are a bunch of Squishies with no armor. if they have heavy AP, Go spirit visage, if they have more AD, Deadmans.
Run Fervor and 29% attack speed in your runes.
tbh i find that alot of people end up being unable to carry with a champion because they simply dont have the right foundation built to enable them to do so.
A bronzie with only 2 runepages will find himself severely limited in terms of preperation for his lane matchups, and also he will be more limited to what type of champions he can effectivly use, as opposed to someone who has 8 or more Runepages.
Remember, Runes and Masteries matter! [zombie-brand-mindblown]
