btw. I am not sure if anyone has noticed this yet, but Moonkin Form is a talent in the "common" druid talent tree. So this most likely indicates that for balance druids the moonkin form might be an optional feature? Or well at least I hope that balance druids won't be required AGAIN to spend talent points to unlock a core feature of the spec.

I think you mean the ability in the center of the druid talent tree? This is the icon for the currently existing talent Wild Charge.
Dunno what the arrows are supposed to mean.
