After playing arcane, frost and fire this expansion I decided to go with frost because its suits me best. So Iv made this little guide on how to play it in PvP (BGs/RBGs). For all those guides on web are wrong due to one mistunderstanding/underestimating it.
First of all stats. Keep it in balance, because if you go full crit, you will have very slow casts, you dont want that. So my recommendation is to keep haste somewhere at 8-10%. I play Night Elf which gives 1% crit during the day 1% haste in the night.
Then most important stat is critial strike. Because we are trying to balance it out and get as much from it as possible, try to get 15-16% of crit. With shatter its x1.5 + 50% vs frozen targets.
Mastery ideal is 11% where we get +20% buff dmg on frozen orb. Any more is not worth due to diminishing return and overall mastery aint that great for a frost mage. We also get Icecles. This plays huge deal in frost mage performance in PvP.
Because frost is not as dumb as fire. it is considered by many people frost aint no good. But thats no true if handled well.
15 lvl talents I recommend Lonely Winter for bigger spell hits. Rather important for finishing enemy off after Glacial Spike. (For those who dont like to have a pet around)
25 lvl talents I recomend Ice Floes. 3 charges casting while moving on low cd. Better than shimmer and we keep our blink.
30 lvl talent Incanterâs Flow all the way.
35 lvl talent Frozen Touch, nothing better here really.
40 lvl talents Ring of Frost or Frigid Winds, but I recomend ring with venthyr Door of Shadows. You can jump into enemies, blind them and then a cast ring beneth them.
45 lvl talents Comet Storm - huge part with Glacial spike combo.
50 lvl talent Glacial Spike - now from what I saw and been reading it is considered that Ray of Frost is the way to go, its not.
In order to gain full frost potencial out and have some SERIOUS dmg, Glacial Spike is crucial.
With these talents the idea is the to get 5x Icicles so that Glacial spike can be cast and some procs Brain Freeze/Fingers of Frost. Once 5x Icecles are stored with Fingers of Frost/Brain Freeze, get Ice Floe up, pop your burst trinket (Icy Veins if you use it, but I recommend do not) (Ice Floes up for Glacial spike being casted while moving to make it difficult for your enemy. Also helps with with knock backs. Glacial Spike is a long cast so you dont want it to get interrupted by some knock back, thats what Ice Floes is for. It also protects your spell cast from being interrupted by Alter Time.) and right after you get your spike off, the target is rooted for 4 seconds, best time to pop your Comet Storm which every hit should be crit because of target being frozen from spike.
Right before Coment Storm hits the target, global cooldown should be off and you can hit the target with your instants at the same time with Comet Storm. This should take lot of hp from the enemy, somewhere around 40-60% hp gone. When this happens, you just finish the target with your stored Brain Freeze/Fingers of Frost procs. Or you can keep up the presure with Frozen Orb + instants.
2nd scenario with Comet Storm on cooldown after you spike your target is Frostbolt + Flury/Fingers of Frost proc. Not as sudden as Spike+Coment Storm+instants, but works aswell.
3rd sceneario is get to Spike ready + Flurry rdy. Cast Flurry in order to get Winterâs Chill debuff on a target, pop Ice Floes (to protect your cast from knock backs + being able to cast while moving) start casting Spike into Coment Storm + Fingers or Frost if you got it/Frozen Orb/.
As frostmage you can keep doing this over and over.
Honor talents
Frostbite - This will help to get some ârandomâ damage out. Better to use Ice Lance on it. Before you would get your Frostbolt off, root will be gone. Frostbite is also very useful vs melees, will help you to survive longer. Can with with Deep Shatter and Ice Form.
Ice Form - You also need this. Keep in mind that Ice Form is not just a burst cooldown but a tool cooldown as well. Makes you immune to stuns and knock backs for 15 sec. This play huge part vs melees especialy rogues while defending a base. As frost with Ice Form you will find beating rogues easy, they wont stun you. Same goes for warriors. If you ever defend a base, you will need Ice Form.
Concentrated Coolness - gives you control over Frozen orb, necessary.
Deep Shatter - Instead of Frostbite (losing roots) I recommend using it with Ice Form up or if youâr free of interrupts in a situation, otherwise ur risking interrupt and therefore dmg delay.
If you try this out, you will find Frost aint so bad at all. Its just this broken meta.
