Taken a second look at the whole package.
My best likes:
- exploration rules
- deadly strike (but could be better named and explained, it's just a weapon dice multiplier)
- druid's wildshape
- druid's circles
- replacements for class bonus skills
- paladin's oaths
Promising, need work:
- multiattack: I don't think any non-Fighter needs this, and could be more flexible (i.e. pick one boost of either type every time)
- ranger's favored enemy: very cool, but benefits are gained at weird levels, and why the silly names? Why not just "Favored Enemy: Humanoids"?
My worst dislike:
- skills... the whole system now looks totally f'up to me
- feats not being optional anymore, required for basic combat actions and exploration tasks
- losing Fighting Styles
- Arcane Recovery: how to take a potentially interesting idea for a new Arcane Tradition benefit, and turn it into a Wizard-mandatory feature that nobody asked for
- Sneak Attack has nothing "sneaky" left, it's practically a new version of Power Attack
EDIT: Has anyone noticed that "Casting in armor" does not specifically mention arcane casters? Does this mean that Clerics are affected also?
