I'm wondering why are Fractals part of the Core Masteries. Fractals are like Dungeons and Raids, and certainly not played by everyone. I gave Fractals a couple of tries and never liked it. Because of that, all the XP's I earn in Core are simply wasted and go to trash. Perhaps Fractals, like Raids, should have its own set of separate Masteries, and a lot of players would stop wasting XP's while playing Core.
