Fireball - Favors high haste.
Frostfire Bolt - Favors high mastery.
Living Bomb - Favors high mastery.
Molten Armor - Favors low crit.
Pyroblast - PvP Glyph
Traditional wisdom suggests that you'll pick either FB or FFB and use LB/MA, but later in the expansion, we might start to see people use both FB and FFB and skip MA. I suspect LB will always be used.
I don't see Pyroblast being a major PvE glyph. Fireball is the only spell cast enough where a pure 5% crit on itself would help more than a 2% crit buff across the board (MA glyph) and Living Bomb seems like a shoe in. If you start with FB/MA being stronger than PB glyph, the only chance you'd use it is if it can beat out LB, and that seems unlikely.
Meanwhile, in PvP, you will mostly be casting mobile scorch, with Pyroblasts on Hot Streak. This leaves you free to use LB/MA/PB as your major glyphs.
