What? You can max out at 463 and still have plenty of problems progressing from there. I hate this idea that Dungeons give you everything you need to move on, they get your foot in the door but the people at the top (IE: The Hardcore Progression Raiders) make grinding your dailies and getting the Valor gear a priority.
Its also insanely annoying to A. Have to grind 1 rep to be able to do 2 others you want and B. Use Valor you've already earned elsewhere. Without doing the grind, Valor is kinda useless.
