I still prefer the idea of skills complementing each other to create better effects (like your skill in a weapon being added to your Lore skill for identifying weapons of that type). The "unlocking" of skills sounds too much like skill trees, which I understand but they can be annoying. I like the greater openness of the way BW does it, but think that it would be cool if there were discoverable benefits such as your Meditation level being added to 1/2 your Int or Wis to give you your maximum number of knowable spells, rather than just the Int or Wis. That would give an additional benefit to an often derided skill and make it a viable second option for casters. It even makes logical sense (Meditation being an ability to control the focus of the mind thereby allows you greater capacity for remembering spells).
Kill 'em all, let the sysadmin sort 'em out.
