How to clear with frost spells?

Im playing a cold damage only bloodmage and dont know how to clear anymore.
Until now i used Cast on Freeze Comet with cold staff basic attacks to trigger the Comet.

But with CoF Comet gone, what now?

- Staff basic attacks? Hard to scale damage.
- Frostbolts? Low damage, low clear... it's a combo spell
- Frost Bomb? Detonation time takes too long.
- Cold Snap? Way too clunky with frostbolt travel speed and low aoe
- Frost Wall? Good, but to my knowledge there is no way to have it explode on small enemies.
- Manual cast Comet? Too slow and interrupted easily.
- Eye of Winter? Possible, but the mana cost (and thus life cost) are too high to sustain.
- Dual Cast on Freeze and Crit? Can't charge energy for two at the same time.

The only spell I haven't really touched is Ice Nova for similiar reasons as Cold Snap

I'm still using cof in my build, I added all the meta energy nodes I could and added as many jewel nodes as well adding in meta energy jewels about 6 of them. I also added cold snap to my bars and the COF still goes off every pack. While definitely not as fast it's still quite nice. I spam the charged comet as well. Clearing t7 pretty quickly

Cold snap is nice because you can just cold snap frozen enemies, thinking of trying to incorporate eye of winter for added sustain DMG but for now comets still clearing mainly

I was just going to make a post of this.

Would you guys be able to elaborate more on utilizing Comet/Energy investment?

Thanks.
