I've played countless ranked games and either I do really good or my team just doesn't cut it. Some one eventually feeds or just point bank gives up. Is there anyway I can improve my chances at winning and finally climb out of the dark deep hole of the bronze rank?
What do you mean "countless?" You've only played 33 ranked games this season. It usually takes at least 100 for someone to climb a whole division.
Your cs/min is very low. You need to go into custom games and work on it. 15 cs is equivalent gold to a kill and right now your cs is so low it's like have 5-6 less kills by the end of the game. The only time your cs/min should be less than 5 is if you are a jungler or support.
Some of your rune/mastery pages are not optimal at all. Look at champion.gg or probuilds.net to see what runes/masteries high elo players use.
You die waaaayyy too much. You should be able to get 3 kills or assists for every death you get. You should use a replay program like replay.gg or skinspotlights replay and look at how you are dying. Any time you die you should look for mistakes you made because if you die it usually means you made a mistake.
Trust me, it's possible to climb out bronze. I've done it for the past 2 seasons. Good luck.
my team just doesn't cut it. Some one eventually feeds or just point bank gives up.
One thing: Blaming your team for your loss is the quickest way to stay in Bronze, because if you attribute the loss to one person, you won't be examining your mistakes or bad decisions.
I've had to climb out of bronze every season I've played in (4, 5 and 6); provisionals in new seasons always dump me in bronze.
Randomonium gave a lot of good advice in his answer. Let me stress this additional point, and I'll note it comes from my challenger coach:
"Don't die. I know it sounds stupid, but really, it's the most important thing. If you're dead [I'm an ADC], you're not dealing damage or getting gold and XP. If you're not getting gold or XP, you're falling behind. If you're not dealing damage for your team, you're not fulfilling your role. Worse, you're giving gold and XP to the enemy team. So it's really, really important not to die."
Another important note: if your opposing botlane gets a kill or two and they're ahead, the answer is not to try to kill them to catch up. They're ahead, and will have an easier time killing you. Farm, and wait for them to get overconfident and mess up. THEN kill them. If they never get overconfident and mess up, they might be the strongest people on the opposing team. In that case, stalling them lets the better people on your team get ahead of the worse people on their team.
Use ONLY 2-3 champions per role. Learn matchups, and improve immensely.
Adc role or jungle is your chance
Countless? You mean like, 30 games? Try 1000+ with 1 champ and then play ranked
Git gud
dude. Play 5 men pre and you get outta there in no time.
Ride the freelo train while you can.
