In theory, true. However, I don't think it'll be too long until spoiler sites post such information. "X Creature has Y ability. I learned Y abiity fighting them when my perception was at Z". Then the next person comes along and says they leanred it at Z-1, and the next at Z-3, and so on and so forth, until they narrow down the actual number your perception has to reach in order to capture the skill.

What I would like to see is a random factor that is assigned per account, akin to the random taper that was applied in Asheron's Call at it's release. Randomly assign each skill a base target number for learning. Then randomly assign a base target number modifier that falls in a specified range. It would look something like this:

Actual Number= Base Number(r) + Random Number(r) (Number selected from a range -15 to +30).

That way it's highly improbable that any two people that know each other will learn a given skill at the same perception level. Some people just learn things quicker than others.
