Even that I will use the current API, I couldnt find info regards this:

1) Can you get Player Stats like: Rampages, Triple Kills, Stacked camps, Wards placed, AVG Last hits, etc.. You know the data that is on your Dota 2 Profile
2) Can you get info if a player is in Low Priority / Remaining games?
3) Current Rank (Solo and Team)

Sorry, I'm new to this API but couldnt find any info about this aside Matches/Heroes/etc, and those are things I will need to work on a personal project.
Thanks for your time, any info will be helpful!
