pillar of frost / cancel aura question

Does glyphed pillar work if already under cc?
bump this, NEED TO KNO!
Go test it out?
I'm not sure, I don't use the glyphed pillar. I rarely use the pillar at all.

You really should use it every chance you get.

As for the glyph question, I have no idea having never used it before.
