Way to fix frost mages PvE dps?

(Without going overboard)

So I'm leveling a mage again (moar mages) and was reading an old post about frost mages PvE dps and it being bad (many people, like me, would love to dps as frost) and so not to make a necro'd post I thought I ought to make a new one. Annnnyyy who, the suggestion is as follows:

So we can't freeze mobs/bosses/stuff in raids so our "while frozen" spells/effects/mastery doesn't do much but give them a mild cold. Instead of buffing our damage (and making more mage burst in pvp QQ) why don't the devs just try making it where if a target cannot be frozen, it gets a debuff that treats our spells on them as frozen. That way, we can be balanced so we have competitive dps in a raid environment, without, y'know frost-busting people in pvp cause are damage inflates by like 50% on frozen targets.

This has probably been suggested times before, just couldn't find any threads on it.

If you have a better suggestion, go ahead and offer it up.

Don't like it? Love it? Smell it? Share about why, make a contribution.
You basically described Fingers of Frost, only Frostbolt is no longer affected by it.

Don't worry. Frost will be doing just fine in 4.2. Gear scaling is looking pretty promising for the spec.
Ignore the people who say frost is not PvE viable, if you actually know what you are doing it is fine already. As Steehl pointed out, Fingers of Frost is already a mechanic that lets you get the frozen bonus against targets that are immune to freeze, and Deep Freeze similarly deals damage instead of freezing on bosses.
Maybe a slight buff in Frostbolt's damage? Maybe a damage buff to Frostbolt when Fingers of Frost is active? Not anything big, but enough to boost Frost PvE DPS some.
Frost's dps is looking very good right now. The only changes I'd like to see us a reduction in waterbolt cast range ( by like 2 yards to fix the max range nova targeting) and around a 20-25% increase to blizzards damage.
