I think it's poorly designed overall
-Wizards (espcially with the redesigned elf) and sorcerers get more powerful, druids and clerics are slightly nerfed, and every other class gets a slight boost except the fighter (since everyone gets feats every 2 levels instead of evey 3 levels, making the fighter less special).
However though there are many things that make spellcasters even more powerful, for example feats like power attack and improved trip are heavily nerfed. The system discourages multiclassing, which won't bother the spellcasters at all but severely affected the nonspellcasters. Between nerfing most of the good combat feats, the boosts to the wizard and sorcerer, and discouraging multiclassing I'll say the gap between casters and noncasters has widened.
