Discovered a fun build, looking for help improving it

So I usually use Energy as my Resource system. I have since devored some time to my Rogue, using Discordance on a dagger. I use Blinkstrike/Swap/ and eventually shatter. This build seems super good, but laking true damage output. My blinkstrike heroic skill is at 30, and my weapon damage is like 9000-16000. I am using Scoundrel to boost dps a little. Any other suggestions on ann ice toon?

Frozen, Permafrost, Frostbiting… etc
