How to get plat from gold 5.

Really the difference from Gold to Plat is good decisions being made on a more consistent basis. More focus on pushing objectives when you have a chance and less overstaying. More passive play when you don't have vision, and knowing when to be aggressive when you do.

That's pretty much it in a nutshell. That goes for every rank... those areas, among other things, improve more and more as you go up.

Objective priority, adc priority, and vision... that basically sums it up. if you get baron with an open inhib up then you still need to be in gold
