You may have misinterpreted my post. I was saying that Blizzard may not have wanted AoE-fests (even though we do have a good bit of AoE in various instances), but at the same time, Blizzard AoE needs a huge buff, as you indicated. I totally agree with you.
Many other specs have strong AoE and Frost needs to be better. It doesn't have to be the best, but *at least* having it work with FoF would be great.
Here's to hoping for results in future patches.
