How I'm climbing the ladder
I started playing back in season 4 and when I finally reached 30 and could play ranked I was placed Silver 4. I know that's not the best, but since that was where I started I was happy. I took about an 8 month hiatus and just recently came back 2 weeks ago. After doing my prelims for season 5 I was placed Bronze 5. I had heard horror stories and witnessed some as I steadily tried climbing my way out.
This morning I just reached Bronze 4 and I know that isn't much, but it is giving me hope. I spent several games trying to figure out the best strategy to get out of B5 and I stumbled upon Sivir. I had never really done ADC before, but I found out that I am decent at it. I'm not the best at CSing or even having the best KDR, but what I have discovered is that in order to get out of B5 it is important to play the objective. If you are ADC you should take the towers and push lanes.
Also, being friendly with teammates and opponents alike can yield wonderful benefits. It's just as the saying goes, "You can catch more bees with honey than with vinegar."
That's just my opinion and experiences with climbing out of B5
