3E has been simplified in some ways and made much easier to run, but oversimplified in others, which I feel detracts from the game. On the other hand, 3E is much more complicated than other versions of D&D.
Good simplifications- Only three different saves that make sense, AC starts at 10 and increases, roll d20 and add BAB or skill bonus and compare to a DC, all stats use the same ability score modifiers. All of these changes make the game much easier to run on the poor DM.
Bad simplifications- 1) Characters automatically gain proficiency with whole classes of weapons. I feel this detracts from the game- in real life, martially trained people only know how to use a handful of weapons well, and of those, only maybe one or two in a truly competent manner. It just strikes me as an overhomogenization of class abilities, meant to appeal to people who were frustrated in 1E and 2E when their character found a weapon they could not immediately use.
2) Cleric domains and clerical spells are too similar between different gods. IMO, the base cleric spell list doesn't focus on spells every deity would bestow on its followers. Sure, the cleric gets two domains and their powers to make him a little different than every other cleric, but this really isn't enough. I think the cleric base list should be much smaller, and expand the domains by 4-5 spells per level to generate truly different clerics.
3) While the CR/EL system is a decent guide for the DM in making encounters, I have seen LOTS of players get very bent out of shape when encounters of a higher EL than the party level are thrown at them. They seem to think it is unfair, or that the DM is cheating. While this really isn't a rules gripe, I think that by presenting the CR system in the way they did, a lot of people look at it as canon rather than as a guide for the DM to determine how tough a given encounter would be for the party.
3E is more complicated in regards to feat selection and keeping track of monster and NPC feats during a fight. Don't get me wrong, I really like the idea of feats to customize a character, but they can be a pain to keep track of. Also, it irks me a little than 95% of all the feats out there are combat oriented. Why are there no "official" non-combat feats?
I guess my last point is more of a personal preference thing, but does it seem to anyone else that the rules system of 3E is MUCH more geared towards combat and fighting than the other editions? Not that this means that 3E is "dumbed down", but it does seem directed at a different style of play than 1E or 2E. This only seems to be reinforced by virtually the all-combat feats, maximized and empowered spells being tossed like crazy at higher levels, and the focus on almost every official WoTC adventure on huge numbers of combats.
Ok, I'm done now. Sorry for the book.
