Frostfire BoltFollow

Ello people.

I don't know if the spell is called "Frostfire Bolt", but it was something like it. What i am wondering is how it will work and where will it lie in the trees. I mean like will it have the damage bonus from ice shards and stuff when the spell crits and can you have it to ignite aswell? Anyone that's playing the beta might know i guess :) It would be awesome if you replace frostbolt with it and then do a shatter crit combo etc.
