Prot warrior glyphs are pretty common sense, prime glyphs should be revenge/shield slam/ and devestate not much option there. Major glyphs I go with Long Charge/shockwave/Sunder however these are to an extent merely based on what I prefer and there really is no perfect choices. Minor glyphs, the same goes for minor i use battle/command/and demo shout.
As for Mastery I am currently all reforged mastery for the most part using the highest changable stat just because im pretty close to be unhittable. however numbers are currently being crunched (I am sure by multiple people) and they are figuring out the exact numbers we should be reforging for, I read something about keeping dodge about 21.6 and parry above 21.44 but I am pretty sure there is no exact answer to this yet.
