Wouldn't this mean that magic is somewhat better in terms that it ignores protection, seems like they are trying to [secretly] buff magic by nerfing the other skillsets with the more need of DEX.
Magic doesn't ignore protection. Magic ignores protection in regards to critical. Think Windmill. That's what people mean when they say "ignore protection." And even then, it's the intermediate spells, blaze and meteor swarm, not all of magic.
