Two concerns:
1. If all the racial fluff was going to be given out free on Design & Development articles, then should I have paid for the Races & Classes book? Taking information out of a book I've already purchased and putting that same information (if not exact) on the Web dilutes both formats.
2. What are we going to see in the Player's Handbook? Seriously, will the Halfling entry be yet ANOTHER description of plucky, river travelers? I understand that previews will include the inevitable spoiler, but the R&C book promised to expand upon the information presented in the PHB. This latest "design" article feels like a copy&paste job of the PHB race entry.
I feel that we shouldn't be too picky about free preview material, but when it closely matches material that I've already PAID for, I get a little irritated.
