Build Simulator
Before people start complaining about how there already are build sims, keep this in mind... I've tried them all. My problem with them is that they're rarely up to date, and that makes them horribly inaccurate. I'm proposing riot makes a simulator in it's item build page, that just tells you what your stats will be with a specific item.
Considering the fact that all of that data is in the game already, it shouldn't be obscenely difficult, and it would help out new players who are trying out different things. Thank you for reading this post, and please think about this idea!
. Just put boots in #2 and swap 3 and 4 and it's a good build; it also lets you put in your own build and compare survivability/damage output/utility/gold cost/etc.
