Even if you play well, someone is fed and you're an ADC or MID (someone squishy) you're going to die many times. If you're doing well and there is a fed assassin you'll have to pray they don't target you. If there is a fed assassin for example Zed, Talon, Rengar, or Leblanc you're going to get killed in a second. You have to rely on your team. It's a 5 verse 5 game.
I kinda feel bad
good positioning makes it hard to assassinate. you don't have to rely on your team to peel for you, it's your job to stay with them in a reasonable spot in fights
LeBlanc W R Q E
Fizz R E-flash Q
Olaf/Rengar ('nuff said)
Zed W R E Q R
Shit isn't going to be in your hands 100% of the time. It's a team game, whether you're playing solo Q or with 4 other friends, and you're not always gonna be able to save yourself. Especially when you're playing a carry like Jinx, whose only form of outplay is to flash out of any major source of damage and then pray you can orbwalk well enough to kill them before they kill you.
i'm gonna stop replying to you. "you're wrong i'm right" whatever
champions using resources to gapclose should never 100-0 you, ever.
zed: buy qss
rengar: ward his jungle camps
fizz: don't get hit by ult
so yeah, basically what i said. don't put yourself in a shit position and you won't die. not all fights are in mid lane, and even immobile adcs probably have peel for themselves (condemn/draven e) and flash.
picking a champion like jinx without seeing some of their comp already is stupid in itself
oh, and if someone is that fed or whatever you're going to respond with, you probably should tell your team to buy lockets or something. if it's a good idea, your team will get it.
