My skinning trees are maxed and I have like over 40 knowledge points just sitting around. This was the case last xpac too. I propose that once we max out our trees, let us dump our knowledge that we accumulate into individual stats like finesse or resourcefulness. That way it’s not pointless to do professions once we’re maxed, and it rewards people that stick to that profession.
I don’t think they’ll do that since that creates an unequal divide. The point is that you are able to max things out eventually and be on equal grounds in all areas at that point, or you’ll get even by specializing into one particular skill.
Creating a “rich gets richer” environment isn’t exactly a good idea. However, with that said, we do actually get something from that knowledge: Artisan’s Acuity, which you can use to buy reagents once you have bought all of the other recipes.
