The perks and perk choices actually limit your character development to the point where you cannot 100% everything like you could in other TES games. you actually have to choose your role.
Nonsense. You can STILL get all your skills to 100. The only difference now, is that you have perks and can't max them out. Yet half of them are abilities. Tell me, are you playing a different role when you can chop heads off? Or open master locks simply more easily? Axe versus swords should be skills in the first place.
You could max out every skill in Morrowind, but you'd be playing OUTSIDE your role. It's not the developer's fault if you can't follow it, if you decide to spend all your hard earned money on leveling up some skills. Besides, when you choose a class, you make sure every other skills are below an acceptable level. Spear is a minor skill? You'll miss 20 times out of 21, because you're playing outside your role.
Yes you can be a JoaT but you will be a very limited one whereas in Oblivion I could, nay, I had to level in a way to maximize my gains (x5 multiplier) least I get trapped in the crap level scale, limiting the number of different types of characters I could build.
That's because you had to choose which type of character you are at the beginning of the game. Skyrim allows you anything because you haven't chosen it yet. In Oblivion, different classes mean you level up differently, it's a consequence to the class you chose. You're not limited in the different types of character you can build, but your character is mostly built when you chose your class.
In an anologue way, if you wanted to be a Nord warrior who uses claymores, chops-off heads, has is heavy armor not weighting anything or smiths dragon armor, you
had to level up in a certain way.
