Most people use some variant of the following:

There's several ways to construct the macro - in general, the goal is to create something that will a) summon the pet if it is not out/dead; and b) activate the WE Freeze targeting reticule if the pet is up.

In general, PoM is quite weak for a frost build and Deep Freeze is considered quite a bit better. PoM will usually not really help your burst since you could often cast an Ice Lance instead for almost as much damage. PoMing a polymorph is probably the best use, but it can't really compared to a stun on a significantly shorter cooldown.

You are 1) Not building your frost spec correctly, 2) not using your frost spec correctly, 3) have not been paying attention to frost mages in arena, or 4) a combination of 1, 2, and 3. I was a frost mage back in BC, and have continued to be Frost for both arena and raiding with my secondary spec being Arcane PvE. If you're heartset, it's even quite possible to build a PvP/PvE frost spec that specializes in AoE raid damage and control, which translates well to PvP in general. Unfortunately, I'm at work at the moment and so cannot link any talent calculator so I can't spout an exmple out for another two hours or so. I will do so at the earliest opportunity!

As has been mentioned, PoM doesn't really do much for Frost, even with the +30% crit. So here's a Season 6 breakdown of specs, coming from someone who has played deep in all three trees in Arena and battlegrounds.

Arcane: With the various talent changes since the 'original' WotLK tree setup, Arcane has lost a fair bit of its 'umph' in Arena, but isn't exactly a slouch. It has high spellpower and comeback potential, and in any setup where you can get away [likely through instant Invisibility] the correct glyphs can give you another go at bursting down an opponent. The problem comes with actually disengaging. Even with a few points in frost and frost armor, your get-away potential is relatively poor with only a powerful Blink, single shot of Ice Block, and Frost Novas for rooting. You are especially potent against other spellcasters because of your high potential for resistances and misses, but not very strong against melee even if you take the Intx1.5=+Armor talent, since your mana can only take so much of a beating through mana shield. When allowed to do uninterrupted DPS cycles you can smash most opponents in short order, which is good because you probably won't get many, much less long, opportunities to do so.

--Stats: Spellpower and Crit are the name of the game once you have survivability of an HP pool and appreciable resilience. Spirit is useful in longer matches but should not be a priority. Intelligence is powerful as it boosts mana, regen, crit, and spellpower. Make sure you have enough hit and penetration to be viable, although this is not to say that hit capping against a Belf priest should be your top priority.

Fire: Fire's problem lays in how PvE focused it is even with PvP flavor talents. The problem with fire's PvP talents is that they simply do not increase your survivability enough. Another problem is access to truly powerful burst because of your reliance on procs for instant casts and the length of fireball casting. In twos or threes, fire is likely unable to have the peeling and isolation necessary to do well. In fives, fire has much more potential because of its ability to selectively burst, however, and AoE with DB, BW, and FS. The flip side is that without a team that can and does peel you will drop even faster. Assuming your team setup and strategy is favorable, your can do well, at least in the lower ratings [speaking from experience, with the lower rating caveat from the limit of that experience]. Timing a Living Bomb explosion with Dragon's Breath --> instant FS = boomboom. For single target this would be more like LB explosion, Fireball and instant Pyro. Getting Death Grip and face pwned = not so hot. You can only burn hot as long as you can sustain yourself, so Mana gem bonuses are important as well as other mana shaving.

--Stats: With recent stat changes, spirit gear is not a joke for fire considering the crit and regen you gain from it. Fire needs as much burst and longevity as it can get, which means Spellpower, Crit, and Stamina are your priorities with an eye to resilience if you have a healer keeping you standing.

Frost Frost's success in PvP hasn't really changed all that much, or should be looked at as 'the more things change...'. It's not the god it was in BC for a lot of reasons, but has never become weak. Ice Barrier with Shattered Barrier makes your access to Frost Nova rooting practically prolific even without glyphs, and Frostbite is still an essential. Water Elemental is what it always has been: extra damage with Freeze effects. You get double Ice Block, which in longer matches can actually become three (I have yet to see the chance for four). Short cast nuke, Ice Lance, shatter, hasn't changed. The addition of Deep Freeze is critical, even with the thirty second cooldown. Barring instagib you WILL have a chance to use it, if for no other reason that Fingers of Frost. For all of the potential of Frost, however, once your mana is out, you're done. One Evocate and at most two Mana Gem cooldowns are all you have, so glyphing and 2pc T7 are essential to your longevity. You last much longer than Fire in terms of mana, but do not have the recovery power of Arcane, so once your [albiet effectively large] fuel tank runs out you're effectively done.

--Stats: Spellpower and Haste are your focus stats after you have a comfortable HP pool, mana pool, and resilience. Spirit should be avoided. PvP gear and Shatter make crit very easily obtained and less useful because of your focus on speed over more crits like fire and arcane. This means that various PvE gear becomes very attractive once you have enough resilience because there are many many items itemized Int/Stam/SP/Haste and ways to splash just enough hit to meet your neets. More and better PvP is always good for you, but a slot item with haste is often better than the clone item with crit.


All of that said, keep in mind that there is a good reason for each spec to get PvP gear, especially with the latest batch of Wintergrasp items [break trinkets with haste, hit, or spellpower instead of resilience]. Keep in mind that the devs are very conscious of the need players have of mixing a little hit in with their spec's primary chase stats, the reason why you'll see clone-value items with the same template and just trading hit, haste, crit, and spirit. This lets you be far more selective about what PvE gear you do include. Glyphs are somewhat spec and preference dependant, but Mana Gem, Evocation, and armor-of-choice are all strong contenders. It's usually better to focus on longevity and mana over damage when choosing glyphs, but burst is crucial to arenas. YMMV.
