just wanted to say that imo, wotc decided they couldn't compete with 3.5. I mean, there really aren't any fundamental flaws (the sort appropriate to an edition change) that you could fix. I cant think of any at least. plus, smaller problems are easily rectified by house rules. so wotc really had to do something like this in order to make a new edition (which they were going to do no matter what to sell books, campaigns, etc). but at least they can change it back again to sell even more stuff.
