They're all up now, I maybe should mention.
I'm really impressed by it. No specializations listed, though.
Some of it is streamlined, which I know people hate seeing that word. There's "Elemental Weapons" which gives the group elemental damage based on the staff of the caster, instead of different spells for each element. Hexes have been cut down to two spells, but they each have an upgrade that improves them to being like a different hex.
But at the same time, others have been well expanded. Rogue has a tree that's largely dedicated to moving threat around. Warriors have a lot more than just their weapon trees.
