Not a fan of the new masteries
Riot dumbed down the masteries big time. They also took away the uniqueness a summoner could spec their champion. Say, if I wanted to put all 30 points in Resolve for as much tankiness as possible. It will not let me, It makes me split points to only have put 18 in one row. That is not how I want to play my champions. Then being forced to take 2 options that I do not want, I neither want to move 12% in brush and river nor do I want 2 less damage from champions and minion.......This is not how I want to play my champion, this does not benefit my playstyle for whichever champ I choose.
They also combine a lot old mastery abilities together. In the Ferocity line, if your damage scales only off of AD, you will be getting split abilities with both AD and AP. How does this define your roll if Riot has made it so you only have 2 chooses? They no longer let you choose the path you want for your champion, it is chosen for you. A or B
