If people don't care that over time Beth has cut half of the series' original skills out, they're probably unlikely to care whether they get to pick a name to go on a menu somewhere. Don't get me wrong, I was kinda bummed too at first, but when you actually think about how little your choice of class actually amounts to, the new system sounds better by far. We'll see though.
Also,
I don't get this. Shouldn't it get harder to level up as you get to higher levels? Why make you level up faster when you are higher?
Not high character level, high level in a skill. If your Blade is 70 and it raises to 71, that will contribute more to your next level than your Alteration going from 5 to 6.
