Wow, that is completely opposite of the experiences I and a lot of other people I know have had with D20/3.x.
D20/3.x works great for a beer & pretzels kind of game, or one focused mostly on combat, resource management, system mastery, lone-wolf PCs, and dungeon delving. For a game where the DM doesn't want to use the built-in assumptions of D20/3.x for magic levels,
exponential increase in PC power, and doesn't want a superheroes/wuxia style of game, 3.x is a horrible system to use. Likewise,
if you prefer a more narrative style of game, 3.x fails miserably.
Thats cool though- quite a few people love what 3.x did, and if they do, more power to them. Keep playing. 4e has swung the pendulum back in the other direction towards a more
narrative and
cooperative style of play. Have you thought of an interesting monster or magical effect? Cool- just insert it in and play in 4e. I think a lot of us who support and love 4e forgot our experiences during the 1e/2e era- if you want to do something, just do it and don't worry about the fiddly mechanical bits or being able to replicate the ability with feats, magic items or spells. PCs shouldn't be able to do anything and everything a moster does- thats why its a monster/NPC. If it makes for a more fun game and more engaging story, do it.
For me and my group, 3.x D&D swung WAY too far from the roots of D&D and we never felt it was a fulfilling play experience. 4e has returned the core set of assumptions about the game style that was present in 1e/2e, while also allowing us to use the simplified and streamlined mechanical base of 3.x D&D. So put simply, 4e is MORE D&D than almost any other version has been for us. And if you don't like 4e, thats cool too- Pathfinder will support the 3.x playstyle, so everybody wins!
