Not a flame or anything, but we just need more roaming GMs. People would try and RP better if there was always a chance of getting a random XP drop.
Can we stop talking about bakers and seamstresses? What about the stealthy rogue? How about a weapon master teaching at an academy? How about a mage teaching potions? What about a WL bard performing in the square? These are all examples of skills directly applicable to the chosen "adventuring" class of the PC.
I don't disagree with the current requirements for becoming a WL, and I certainly would not want to see the door opened up wide. At a level a month, a new PC would reach 20th after 15 months. That seems a reasonable amount of time to establish that PC as a WL through RP and deeds.
