Drysc does say that the Armory is a click away from the forum icons, but surely Blizzard could take an afternoon and code a little customization into the icons. It seems like everyone else can render icons out of game -- why can't they? There is some good news for those looking for a forum icon update, though: Drysc says that when we're all level 80, we'll probably have new icons yet again, with shiny T7 on our characters.
Which will be great -- until a few big content patches after Wrath, when T9 will be out and we'll all be whining that we're still dressed in T7. Thus goes the circle, the circle of life.
