online is a different realm than just playing offline, with some lan sprinkled in.
also, a slight disappointment, the first rune "wasn't" a shael rune, it just looked that way because of how the crystal was in the first and second screens, the third one shows it as something different, most likely from a deathknights rune sword.
i say this, because the third symbol, is the protoss symbol in starcraft 2. so its like they are representing all of their franchises, like last year when they announced sc2.
hope isn't lost though, they do this stuff all the time, and they are going to make it, its just a matter of "is it now" or "is it going to be announced in a few years"
