Basically, my point is that we have little to no choices as it is. Water Elemental glyph will be essentially a wasted slot next patch since you can just park him wherever, so that leaves IV, IL, and Evo for raiding.
We also have little to no "fun" minors. Momentum is amazing, and that's it. I like Illusion, but the 2m duration for a hefty 30m cooldown is just bullcrap. The others are just stupid, though Loose Mana is a nice one for Arcane (the only specc that uses those useless gems).
It's also not just Frost; all 3 speccs of Mage have little to no good "choice". Fire is pretty mandatory with Combustion glyph, and Fire Blast is good if you're using LB for cleave fights. Besides that, I'd use Evocation because, well, 40% heals are nothing to scoff at for raiding, and I'd replace Fire Blast with Armors for non-cleave fights with AoE physical damage (e.g., Vizier, Blade Lord, etc) because it buffs Molten Armor from 6% Phys reduc to 16%; a nice boost to your defenses and your healers' Mana.
