Skill Tiers

I am considering introducing a new concept to handle characters in d20 based games that have lots of skills, but little skill in combat. These are "skill tiers" inspired by the new Mythic rules Paizo has created. They work much like Mythic Tiers, but they only grant 4+Int modifier skill points per tier and a bonus feat that must be a general (not a part of a specific category of feats like Item Creation, or Metamagic feats), non-combat feat.
