Honestly it's not a bad list, but the idea that mastering mechanics is different than being a top tier player is wrong. If you have truly mastered the mechanics of your mastery and the game itself, you are in the top 1% of players. There are a few names out of place in my opinion, however, but that is to be expected in such a large list. That said, all of these players are good and have a great understanding of their masterie's and the game's mechanics.
