I just wanted to write a quick update--I got the Frostbitten achievement this afternoon on my druid, Hearthyn.
That's right, 5 days after I started seriously trying for it.
For those skeptics out there, I'm going to start farming them on my hunter, Dianara. Here is her kill:
Whoa! Only one.
I was going to finish this on my death knight, but she has quite a few kills already. I wanted to give you an honest showing of exactly how fast you can get this achievement now. So, tonight, I will start farming. I will keep you up to date on my progress. Let the countdown begin!
P.S. For those of you wondering, or who want an absolutely awesome UI, I am using the hybrid Elv/Tukui Nitewolf helped develop. You can find it here: https://github.com/nitewolf121/Tukui/downloads
