310 emblems at 19 a week.. 4 months to complete, assuming you spend NO frost emblems on anything else and you do the daily and weekly every cooldown XD

I'd be a bit concerned about the loss of resiliance on your toons though, you would have to run with what, 600 resiliance? and your HP would be considerably lower than most players in your bracket. Could make for some amazingly well coordinated lava burst target-switching though =)

gogo Frost Emblems!
