There is a screenshot of a balance talent tab at
Relevart's.
Balance masteries for the character show as 8% spell damage, 8% haste, and 12% Eclipse. That is with a 60/0/16 build. I have no idea of his gear (all leather? does leather matter yet?).
It also shows the new Eclipse meter. As anticipated it resembles an EotS capture meter. There is some text discussing the new Eclipse, but to me it looks as if it may be speculative (as if the author hasn't actually used the new mechanism).
The talent tree seems to match the one at MMO (although MMO is missing the prerequisite arrows for OF and IMkF).
