I would like to see, what Keys i pressed and how often i did so. There isnt really a benefit to it, but i like stats as such and the earlier Version Game Summary had it. As Outplayed already captures the apm, it shouldnt be difficult to get a counter for each key pressed during a game. maybe, for league f legends, even a "Time typing" counter which count count the time between pressing enter twice, and the ammount of letters written or words written, i am not really sure about that myself, but "Time spent typing" would be a really interesting thing in my opinion.
Best Regards
