AFTER GAME ITEM STATS
As now there are post game masteries and keystone stats, for example, Dark Harvest: Total damage deal/stacks/times activated; I am expecting to see the same mechanics on items. It can help determine which items fits better the current build. As an example, full Attack Speed Kog'Maw. I want to know how much bonus damage Wits End dealt and in another game, build Rageblade and see which item fit better.
It can potentially improve a player's item choice and overall performance by providing a tool to analyze their items bonus damage/healing/damage blocked/times activated and so on and so forth.
I'm posting this with the hope of receiving some attention from the devs so maybe a feature like this one can be present in the future.
I'll also be happy to know what you guys think about this!
