Resto4Life has published a great run down of the current Druid changes forthcoming in Patch 2.3.
The major changes from my point of view are the addition of Remove and Abolish Poison to Tree of Life and the boost to Tranquility.
I'm less worried by the absence of Remove Curse than Phaelia is - de-cursing is available to more classes than the poison removal is, and I'm called on to shift out of tree for poisons far more than curses. And the boost to the big "get out of wipe free" card of Tranquility is just fabulous news.
Very happy with these tweaks.
