Um, 3.5 was a joke already. It really was just a money grab. Nothing fundamental was changed, nothing was really improved.
But 5.0 is pretty fine overall. They made spellcasters start much stronger, but get less of a power curve, while warriors have been made more interesting. Everyone gets interesting special abilities. A Rogue is a real powerhouse in combat now. Bards are an almost fullblown class. Etc.
