Once again, I would like to point out that these issues could be worked out if there was an enhancement added too the Arcane Archer tree that allowed for using wisdom for damage with bows, similarly to Improved Finesse from the Deepwood Stalker tree. Also, this would allow for better splashes for people who want to be Warpriests of the Silver Flame (Clerics or Favored Souls, or even Paladins for that matter), but have to use bows as their favored weapon. Wis-based Rangers could be pretty awesome if this was added, and the magic aspect of the tree would be much more promising.
Edit: Is there any reason that this would be problematic? Also, Zen Archery allows for wisdom bonus to attack.
