Alignment systems, as a general rule, are straight jackets for roleplay, and D&D's in particular is responsible for amazing amounts of completely retarded character behavior. All it adds to the game is a system that allows morality to impact game mechanics, and that's something I could do without.
Vancian magic is at the top of the list of things that have always felt wrong about D&D, since I was a kid with a Red Box and a bunch of hand-colored dice. It's an interesting and flavorful variant of a magic system, but as the dominant paradigm of all core-class spellcasting, it really, really needs to go.
Classes are the other big reason I favored other RPGs over D&D for most of my gaming history. I'm not interested in recreating traditional fantasy archetypes, or filling specialized roles in hyper-efficient dungeon-delving teams. I want a flexible toolset that I can use to make a wide variety of characters. D&D 3E brought me back with feats, skills, and multiclassing rules that weren't completely insane, but things could still be more flexible. I'm not really asking for fully point-based characters, though. For D&D, I'd say True20's style of generic classes makes the most sense.
It's still basically a race-and-class character system. Honestly, D&D is more flexible than World of Darkness, these days.
I don't think accuracy to the real world is quite the issue, here. The problem is that the alignment system fails to do the very thing that it's supposed to do: Classify and describe the philosophies and moralities of interesting fictional characters. The very fact that people can't agree on what "Chaotic Neutral" means indicates that the system isn't working.
Pretty much what I was going to post.
