Infraction: GLYPHS WILL END MAGES EVERYWHERE
Message to User:
You are by no means required to use the PvE glyphs in PvP. Also, you have no clue that those glyphs will remain unchanged. Stop whining that your proposed PvE upgrades might impact some aspect of PvP and require you to actually make changes to your character before you try to excel at one or the other.
See Wrath Whining sticky for more info.
The frostbolt glyph is phenomenally stupid. Whereas the fire one is a straight out buff in every conceivable way, frostbolt suffers a huge disadvantage for the same benefit. Parity?
Unless I am wrong, the fireball glyph is a nerf to some pvp tactics (like using the dot to keep rogues in the open) and it won't work with trinkets and such that triggers off DoT effects anymore. Saying that however, this pales to the disadvantage that the frostbolt one gives.
