I didn't vote but, I do think WotC should providde eratta updates on their website. As I interpret it one of the main selling/marketing points for 3.5 was a clearer rules base for players of the game. When you have two or three different versions of something that is definitely not a concise and clear rules base. Then again I also believe WotC should provide free downloads of indexes for those books (which have become quite a few in the last year) without them. ((Actually upon further reflection they should be a given in any "rules" book.)
Sharn, Five Nations, Explorer's Guide, Magic of( not to mention it contradicts cannon in the corebook), all the Complete books, Planar HB, PHB2 etc. are all missing indexes. And you know what? People are absolutely right, you vote with your dollars. One of the reasons I have(even though I liked it very much) given up on Eberron as a campaign setting and more than likely will not be buying anymore complete books. It seems that flashy art and glossy pages are more important than practical useability, and I don't agree with that.
As far as broken rules, well if I wanted to spend the time and effort analyzing the books I buy to "fix" them I wouldn't have given WotC so much of my hard earned money. I think that as a consumer I should expect a certain level of quality( once again I'm not talking about pretty pictures or glossy pages) when it comes to a gamebook and its rules.
People say they are just revisions or whatever, but if my player spent his money on a supplement, he should be able to use that supplement without it in anyway contradicting the core rules. The problem with the whole revision thing is expectations and no hard "rule" about which is official. That's where the arguement starts. If I expect a particular fiddly bit to work one way and another player expects it to work another whose "right". What if with my understanding the player would have never picked the option? Finally what if we think we're on the same page until it's used in the game?
Picture it like this if everybody comes to play a game of Monopoly or Clue the basic rules should be consistent. Variants and add ons are a different case. Yes WotC should charge for new books. No they should not "revise" or change already established rules without making that information available to their consumers.
