Even if they did chop content, there's plenty for leveling.

I mean, as Dwarf, I do my Chapter 1, 2 and 3 town quests to get to level 10. I won't be seeing content for Chapter 1, 2, 3 for the Empire (Human) unless I go there from level 1 (it's doable).

On the other hand, I can roll another toon and do the early Empire chapters to see that content.
