Should GMs focus on running the playtest rulebook RAW, or should they integrate direct developer word on how mechanics are supposed to work?
For example, there seems to be a kerfluffle over Lay on Hands. Apparently, Mark Seifter and possibly other Paizo people claim that with Warded Touch (a mandatory feat tax), Lay on Hands does not need a free hand. However, nowhere does this appear in the rulebook RAW.
As another example, sorcerers and wizards are untrained in unarmored defense by RAW, yet the pregenerated Ezren seems to suggest otherwise.
The above are merely examples, howeveer. What should GMs prioritize for the purpose of a consistent playtest, the rulebook RAW, or direct developer word?
