I always wondered what its like to play a 5K or 6K game, as there are many things that I can learn, and not only that, but you will be teamed up with above average players as well and they will be able to give you some advice or tips on where to place your wards if you're a support, or what item best suited for your core heroes.
With this new ranking system, I can now play with and against high ranked players before, and while it is tough, but there are many things that you will learn and players like me will surely improve on how to play the game, especially when you have already decided your primary role, support/core. One of the disadvantages with the MMR Ranking system is when you're playing 1K - 2K games, players barely communicate with you in-game. Most of the time, players doesn't have mics, and there's that language barrier as well (though we have started to establish our own universal langage for Dota 2). With this new ranking system implemented by Valve, will surely help players especially new ones as well.
One of the things that makes Dota 2 community not so friendly, especially with noobs/newbie is this MMR Ranking as well. When the match started, those player who has the highest rank will bully those who have lesser rank, even though game stats shows that the high ranked player played poorly during the match compared to the lower rank. With this new ranking system, they can no longer use the "I have a higher MMR than you" card. There are players who are ranked below 2K, played really well in the game, while those who have 2K - 3K ranks, plays poorly. This time around, everybody will start equally and hopefully this will lead to a better community that what we have right now.
I am happy with the new ranking system that Valve implemented as I am confident that this will help other players, not just me, improve their gameplay and eventually will breed a new set of pro's. Again I commend Valve for this update, although this is not a perfect ranking system, but for sure this is better than the last one.
Hopefully, they will find solution to the problem of players picking their respective roles in the game. As there are times where players picks all core heroes without support, or players who pick a support hero but played it as if it is a carry. I hope to see someday where you are assessed on how well you played for each roles from position 1-5. Valve...
