I think haste stacked nether tempest, as frost or fire (fire sounds like it might be best) is the way to go. It doesn't break fragile CC, amazingly (does not attack polymorphed targets)
Glyph choices are numerous, I think Poly/DF are mandatory-ish, third glyph can be anything - armors against cleaves, evo in 2v2, maybe even ice block?
When I was playing around with it last night it tended to break poly often and kinda had to mold using it around that (stacked healer and shit, one game this hunter ran into the pally i had polyd and broke him out). Maybe it's like mirrors lol. Speaking of glyphs ice lance is the shittttt with tempest.
