1. Talents & Glyphs
Presence of Mind - Benefits arcane and fire more than it does for frost(dps wise), but can still be useful for things like instant cc.
Scorch - Castable while moving with no cooldown, scorch is the most mobile talent you can pick. Excellent for raid progression and any high movement fights. Note that scorch can proc fingers of frost. My personal favorite choice.
Ice Floes - Having a 1min cooldown, less mobile than scorch. Lets you cast 2 spells with a base cast time of less than 4s. This spell is castable while a cast is already in progress, and lasts for 10s or until you cast two spells. This talent is the best for maximizing dps as it allows you run with your frostbolts, providing you don't have to move too much.
Temporal Shield - 25s cd and lasts for 4s. While the 4s buff lasts, it records every bit of damage you take, then once it expires it puts a 6s hot on u that heals the total damage u took in those 4s. Very high survivabilty move if timed properly and can even out heal cauterize if you have it talented and took enough damage. Especially good for taking large hits like the overloads on the stone guard boss. Note that this move is off the global cooldown, so there is no dps loss at all in using this ability. Also usable while stunned, feared etc. Easily the best for raiding once you know the fights and when to expect large amounts of damage.
Ice Barrier - 25s cd and lasts for 1min. Absorbs damage based on your spellpower and is an excellent alternative to temporal shield. Good to use for damage over longer periods of time, and good for progression raiding when you are just getting used to the fights. Also prevents pushback from damage as long as the bubble lasts.
Ring of Frost - A really good choice for adds that can be frozen. Can be used to get some nice shatters off or for some really nice crowd control.
Greater Invisibility - 2.5min cooldown. Turns your invisibility into a super defensive cooldown that just plain rocks. It instantly turns you invisible which dumps your threat, removes two damage over time effects on you, and lasts for 20s unless it's cancelled or you are knocked out. While invisibility lasts and for 3s after it ends, your damage taken is reduced by 90%. This is by far my most favorite of the three for raiding. You're not forced to use iceblock like you sometimes are with cauterize, and you hardly take any damage at all. Time it with major boss mechanics and make your healers proud.
Cauterize - 2min cooldown. When an attack would otherwise kill you, you will be healed 50% of your hp and lose 40% of your hp over 6s. Acts as an auto battle res. Excellent survivability especially if you like to stand in stuff(lol). Usually best to hit iceblock after you cauterize to remove the dot left on you by it, leaving you with a full 50% hp. You can also pop temporal shield or ice barrier as an alternative if you want to save ice block, or just rely on your healers. Very nice ability.
Cold Snap - 3min cooldown. Heals you for 30% of your hp instantly and resets the cooldown of your ice block, frost nova and cone of cold. It is my least favorite for raiding as its more suited for pvp, but still can be useful to remove debuffs or to survive a big hit.
Tier 5: (Mage Bomb)
Nether Tempest - Although not by a huge margine, provides the best single target dps as it can proc brain freeze quite often due to its fast tic damage (with decent rng). Its instant cast makes it a nice mobile talent and can be cast on as many targets as you want.
Living Bomb - This talent has a 1s global cooldown regardless of your haste and is an instant cast, making it another good mobile choice. It has a target limit of 3 and has a chance to proc brain freeze off of each tick, just like nether tempest. Auto explodes if the affected target dies.
Frost Bomb - Has a base cast time of 1.5s and is the only cast time bomb spell which also has a cooldown and detonation time that are affected by haste. Although it is less mobile than the other two spells, it can pack quite a punch and can tear through large groups of mobs for some nice burst aoe damage. Instead of a dot, it does all of its damage when it expires or auto explodes when the affected target dies. When detonated, it always gives a brain freeze proc, making it the most predictable source of brain freeze procs. The aoe explosion also has no target limit.
Tier 6: (Greatly affects playstyle)
Invocation - Evocation has a 10s cooldown, and when you complete an evocation you gain a 25% damage buff for 40s. Although all three talents are relatively balanced, this might be the best of the three if used to max potential. As far as I know, it is being changed in an upcoming patch, making it less annoying for trash etc. Haste becomes even more important with this talent.
Rune of Power - Has a base cast time of 1.5s and replaces your Evocation. It has a 6s cooldown and you can have 2 runes placed at one time lasting 1min each. While standing on these runes, your mana regeneration is increased by 100% and damage is increased by 15%. The least mobile talent of the three. Takes a bit of getting used to, but has a nice animation, as well as some nice periodic healing if you are running Glyph of Evocation.
Incanter's Ward - Gives a passive 6% damage buff and you regen 65% more mana as long as it is off cooldown. When used it will disable the passive buff and apply a bubble that will absorb an amount of damage depending on your spell power for 10s. You will restore up to 18% of your mana and get up to a 30% damage buff for 15s depending on how much damage you take. Has a 25s cooldown. If it were possible to use this every cooldown and get the full benefit, it would be the best talent. Since not all fights have constant aoe damage, it can most of the time perform just as well as invocation.
To sum it all up:
High movement fight and/or predictable damage - Incanters ward
Moderate movement - Invocation or Rune of Power
Glyph of Ice Lance - If there is more than 1 target.
Glyph of Icy Veins - Allows you to pop icy veins and benefit from it once it puts you over 50% haste. Good if you are planning on stacking icy veins with hero or a haste proc. any haste past 50% will just go to waste.
Glyph of Cone of Cold - Really nice for aoe burst and aoe dps increase.
Glyph of Water Elemental - Good for when you don't like giving your pet move/follow commands during an encounter, so that he is always in range for his freeze ability.
** As frost you want to be running Frost Armor, the haste benefits you more than the crit from Molten Armor.
