Kills: To set your enemy behind in gold and XP and give you a temporary leg up, making it easier to hold a lead. Not for extra gold.

CS: Takes priority over kills, your Flash is worth more than 300g early game vs competent opponents. 7 per minute is practical 10 per minute is optimal.

Items: Should be built according to matchup, time, composition, and efficiency. Not because it gives you 100 AD.

If you dont accept and understand these things, even if your playing is above Silver, your true skill level will never increase. Your mechanics may, but your actually game knowledge and potential wont.

And mechanics alone only get you to Gold.
