Now that the Wrath of the Lich King Beta is live, and the patch notes are up, we have some solid information on Druid talents as they're being tested. Here is what the patch revealed:
If you were to invest three points into your Brambles tier three talent, you will not only have the current 75% boost to damage caused by Thorns and Entangling Roots, but your Treants will have their damage boosted by 15%.
In addition, all damage caused by Treants, and any attacks done to you while Barkskin is active, have a 15% chance of dazing the target for three seconds. Actually, Force of Nature, which summons your Treants, is having its cooldown reduced from three minutes to two.
This will be a nifty talent for Moonkin in battlegrounds and arena, although it won't be enough to convert all of those Restoration druids to the ways of the Giant Chicken.
