I'm having trouble with Endless proving grounds as frost. Since gear is scaled down (to 463 i think), I'm not sure what I should be going for in terms of stats. The biggest roadblock for me is the Big Sha right before round 20. You have about 20seconds to burn ~8mil. I use time warp and all CDs, and the closest I've been is about 1%.
I'm speccing NT, invocation and ring of frost, glyph water ele, splitting ice, and CoC. My gear is all gemmed for fire, but I'm going all haste for reforges.
Any one have tips? I can't imagine I'd be able to get the wave30 Sha down if I can't get 20.
I watched the mage from PTR who got to wave 87, that was insane...but I'm not really doing much different than he is, besides not having 5.4 trinkets.

Well, after a couple more attempts I got to wave 23, so I just need to get lucky with procs
