Balance druids everywhere are currently rejoicing. Why, might you ask? Well, you see, the Eclipse energy portion of Lunar Shower has finally been removed from the Mists of Pandaria talent calculator. That it took this long is something else entirely, but that isn't even really the point.
First, I wish to express a slight personal issue with this revelation. When the Pandaria talent calculators were originally released, it was stated directly that Lunar Shower would be "working differently in the future." While I suppose accurate on the most technical levels, reverting a broken talent to the slightly less broken state that it was already in before it was made worse is not working differently.
A bit harsh? To say that Lunar Shower is a broken talent, to suggest that it was always a broken talent? Well, I would apologize or choose better language -- however, this is the case. Lunar Shower has never truly fulfilled the function it was intended to serve, to offer balance druids a mobile DPS option. In defense that the current Lunar Shower on the live servers now is broken, I don't really think I need to put forth much evidence. After all, no one specs into it. Every single guide tells players to avoid it. And there's at least a thread a week complaining about it on the official forums. The issue speaks for itself.
