A blue post in Blizzard's official World of Warcraft forums is probably a common occurrence for some. For others, like player Pangoria, it is an example of grace. The paradox is that Pangoria has noted an improvement on the shaman discussion forum from lack of blue poster communication.

In other words, the various WoW shaman players have been helping each other out in the absence of blue posts. The shaman is the least played class in World of Warcraft, Pangoria said, and perhaps the current trend of support will eventually change that.

As if on cue, Blizzard blue poster Nethaera answered a forum members query regarding possible class changes and shaman buffs in Wrath of the Lich King:

I answered some things in the other thread here on what the current focuses with classes are which in short are bug fixes and any changes the Development Team feel are necessary at this time. Major changes are not being worked on prior to Wrath of the Lich King, but additional changes and adjustments are still possibilities (along with fixes).

Again, though, there is no guarantee of further changes until Wrath and it's unlikely there will be much more. That is still within the discretion of the Development Team, however.

All in all, it's nice to know that amidst the trolling on Blizzard's forums, there are still valid, informative and edifying posts out there.
