Core Dagger/Dagger Back?

This is just for fun, but has anyone tried this yet in Pvp?

Good protection and aura generation, over 600 heals per second, blind on demand, and damage is decent, especially when you can mark 4 stacks of fire at 1200 range. Too early to tell how it does in ranked, but it's a fun build for sure. Best way to fly across the maps. For Dagger weaver, it's too heavily reliant on Focus. But Dagger offhand on core does much better. For those who try it, let me know how the build pans out.
