The issue I'm seeing is that if someone is playing a specialised character where they put all their sexy points into magic or ranged for example, they're rendered completely useless against these mobs who only take 1's and 2's from those attacks.

Some entities, like Skeletron Prime's arms, are immune to everything, which just makes the whole thing an exercise in futility. Have you checked out the status of the boss? Includding it's Pierce and Imunity rates?
