The change is a good one, and there's still abilities that differentiate species, so dwarves still have toughness, and a bunch of other abilities.
Previously a Dwarven wizard was just a really bad choice, and you'd be noticeably less powerful than say an Elven wizard so no-one ever played one.
Now an Elven Wizard for instance has a few bits and pieces that might make them a bit better, but still leave a Dwarven Wizard as a viable choice.
This makes the game far more interesting in every way: players have more interesting builds, more character choices, and can play whatever combinations that they want.
