I have to agree with the OP on all points. I've always had good ideas for characters that were fighters and rogues, but I've never played them because they felt boring to me after a few levels.
I would add rule modularity to the list. It feels like some modules could easily be replaced with a few minutes work. (i.e. low magic setting: characters get +1 to attack, damage, and all defenses every 5 levels. No magic weapons, armor, or neck slot items exist.) Others might take more work. Similarly it feels like you could blur the distinctions between roles by making a generic class for each power source. I'm really hoping for an unearthed arcana type supplement at some point that features that kind of modularity.

I agree with this too though. I love the game, and have no intention of playing anything else right now, but sometimes it feels like something isn't right even when everything makes sense (to me) and everyone is having fun. I'm at a loss to explain it.So that's why I ask - because as much as I like 4E, I cannot escape the feeling it's missing something.
