i think ranked is sort of unfair at low elo

So far i have played about 50 games or ranked and so far i have found it not fun AT ALL and very stressful. This is for the reason that i have played about 30 games or ranked that involve an afk. Whats so wierd is that there seems to be more afks in ranked than in normals. And i can say out of those 30 times about 70 percent of the time the afk is on my team. It almost makes ranked more luck and not skill at lower elo. I cant tell you how much i want gold but i am held down by afk players and toxic little 9 year olds. Not to sound like that cocky gold player but i am gold 4 and i believe i strongly deserve a higher rank than that. But i am always the kid that gets the feeder on his team or the afk. Then even if i do pretty good i still go down in rank. And i think its unfair if i do good and get punished for it because of my team. The way i look at ranked is that i am 20% of the team. And my team is the other 80%. And they have to be good as well and they have to not go afk. Thats why i think that ranked needs a big change and that you should rank up if you do good and you get demoted if you do bad. i feel like that way you can focus on you doing well and if your team does bad it doesnt matter and you still can get the rank that you deserve. Pls reply back on what you think of this issue.
