Frozen Orb in passive tree and skill specialization

[Llama8]

There’s a discussion about it here:

Why the redundant mage talents?

so i’ve been playing a sorcerer today, and i couldn’t help but notice that there’s a fairly low level talent in the base mage tree that convert lightning blast and volcanic orb to frost damage (and grants a freeze rate, etc.) but when i went into those spells individual trees, they had their own option for converting to frost, an option you had to take just to get at the talents that affect freeze rate to begin with. is one or the other planning to be replaced?
