Bit of a small nitpick with the Cunning Mastery Tree...
...but could the positions of the Wanderer and Savagery, and Bandit and Dangerous Game be switched? If Wanderer and Bandit were moved to the right side of the tree, it'd match with the other 'Support' masteries of the tree being on the right side, and the more 'Assassin' masteries being on the left.
