I think Ranger AA remaininf Wis-based would be ok (not ideal) if Elven AA was treated differently and it used either Int or Cha...maybe even seperate it further by giving Ranger "Primal Archer" (or Primal Hunter) and have it be very favored enemy focused...make rangers the king of hunting their favored enemies make it a really huge deal...or you know remove AA from ranger entirely and make DWS their primary ranged tree insteasd of just a crappy melee/ranged mix tree. Leaves room for a third tree for rangers that actually suit the class. (since ARCANE archer doesn't suit it whether ranger is divine or primal)
This could be the start of races getting uniques prestiges to themselves...I'd also say move the PrE access to Racial Tier 1....Actually I'd say you should gain racial stuff (current racial stuff NOT the unique prestige) as you level up automatically (or with enough Racial exclusive AP to max it by Lvl 20) instead of wasting precious Class Enhancement points.
