Here is a compare LIVE vs PTR, done with simulationcraft, calculations from my mage (Ilvl538).

According to my simcraft result the nerf is more than 30%.
LIVE Combustion damage
With Glyph 2 289 618 damage per execution (DPE) (DPS = 26 040) (95sec interval)
PTR Combustion damage
With Glyph 964 602 damage per execution (DPE) (DPS = 10 971) (95 sec interval)
Without Glyph 389 912 damage per execution (DPE) (DPS = 7 852) (52 sec interval)
These are priority stats for my character it might differ from yours. (Ilvl538). (Normalized)
I have around 48% crit in raids.
