My problems with 2e weren't exactly with what it did include but with what it didn't. It didn't go enough. After all the years that 1e was out, gaming had had all kinds of iterative improvements, tweaks and whatnot, and the theory of game-design was significantly advanced. 2e should have been an improvement on 1e; instead it was mostly just a re-hashing of 1e. All of the things that already annoyed me about 1e and D&D in general were retained instead of corrected, updated or improved on.
So, 2e wasn't necessarily bad, it was just blah. By that time, I wasn't interested in the paradigm that it presented anymore, and hadn't been for several years.
