I thought that was a brilliant way to make people want to play different builds because they couldn't max everything out on one character.
I get this, but I think while that worked in New Vegas, it failed in Skyrim. This is why:
With New Vegas, you CAN'T do everything with one character. Different builds play the game different ways, and your factional alliances are different each time, too. The game is set up so you play it for 20-30 hours each with 3-4 different characters (some of which probably won't even reach level cap) before you can say you've completed most of it.
Skryim is not the same way. Skyrim is designed so that you can do everything with one character. Different builds are fun, but ultimately, most people are going to just do all the guilds and quests with 1 or 2 characters. Plus, the fact that loot and monsters level based on the player's level means that by roleplaying like you'd do in NV, you'd be missing out on lots of late-game content.
Whereas in NV, you can access all of the games content by playing several builds for 20-30 hours, Skyrim locks you out of lots of content until you've played like 60 hours with one of your characters.
Sorry if this is convoluted and unclear but I'm sure there are people in this thread who will get what I mean.
