Totally serious.
-werebear’s Maul has no secondary skill, why does Rage need one?
-they are the same type of skill accessed at the same level point.
-Rage has it’s own enhanced damage.
Notice that I mentioned lighting damage as well before hand. Well you can’t really head in that direction because of “lightning fury”, but imagine cold damage.
People have already complained about spirit wolf cold damage and this is the idea that they suggested, much like your suggestion for fire claws.

So what are we going to do? Have vengeance spirit wolves and vengeance fire claws? Pally Druids? No.
But if we think very carefully for a second. What word is very similar to Fury but could be cold damage based? You guessed it yourself because I have good faith in you.
Flurry it is. And right from the online dictionary:
"You can use this phrase to describe a situation in which a large number of attacks happen in a short period of time. For example, “The enemy launched a flurry of attacks against our troops.”
a: a gust of wind
b: a brief light snowfall
plus an argument could be made that fury and zeal are a bit too much alike.
convert X% physical damage in to cold after physical damage buffs and that
makes them more different.
plus an argument can be made that druid elements have a pure physical damage skill(tornado). And that’s entirely a spell, it’s not some halfway point between spell and attack like fire claws that has spell synergies. If tornado can do that then fury can be flurry and be purely elemental.
plus the Druid is a gosh damn mage anyway.
