Look, here's the bottom line for all the haters. It's a casual solo game. It's built on the fundamental illusion of "character advancement". You are killing the same wolves in Rohan that you killed in Bree but the Rohan wolves are so much more 1337 than those wussies in Bree. You wouldn't stand a chance against them unless you were 85 because they create an artificial level difference function that enforces leveling up. But again, it's all an illusion. You don't have to be any better at playing your class. The only requirement is simply that you've played.
Well, eventually people catch on to this illusion and Turbine needs a way to make people believe they are advancing even though they aren't. The game was designed for this by periodically giving away skills and earning traits. As the Developers point out there is a design limitation on continuously placating the casual illusion with new skills every couple of levels.
The solution then is to do a one-time rewrite. You simply take away a bunch of skills and reduce effectiveness, but then given that effectiveness back over time as people level up to 205 or whatever. That keeps people thinking "wow, I'm much more 1337 now, hear me roar" every time their little experience bar flips. It's a good model for keeping people running cheap Kill Boar and Deliver Pie quests almost indefinitely without having to invest in more expensive / creative content.
You could have a game that had no levels. One where people advanced based on achievements. But that doesn't fly here. Better to keep people on the koolaid.
