I think it would be a great addition, if you don't like it, you wouldn't be forced to use it but the people who do want it (and I'm sure there is many) would be happy.
While this isn't an Obsidian game I think J.E Sawyer said it the best: This isn't Options: The Game.
A game needs to have a certain consistency, too many options should not be allowed.
And one such as this is preposterous, it's an RPG people, a role playing game, haven't any of you ever experience action and consequence?
Allowing a "respec" would devalue the entire point of character building.
"But it's optional, so who does it hurt? If you don't like it, don't use it."
Uh-huh. I agree that optional things can be good as it allows both sides to use it to their own leisure.
But this is an RPG for crying out loud.
Respec an entire character you've slowly molded?
Hell no,
even if it's optional.
Some of you simply needs to learn to deal with mistakes and suffer the consequences.
To me, though.. this seems to be the opposite of balance. I don't want to be a demigod -- I didn't see a problem with Oblivion's skill perks. The ones in Skyrim seem to be a bit more powerful, but I really don't think having every perk would give you a godlike character. I would like to "get everything I want", though.. if I'm willing to put in the hours, why shouldn't I be able to make my character extremely powerful? It's more of a restriction of freedom than anything. If I get a PhD in Physics, Mathematics, and Computer Science, I should still be able to do the same for unrelated fields, so long as I put in the effort.
Why do you have to "get everything you want" though?
Again, RolePlayingGame, so roleplay.

Then with what you have said here about balance... then it should be ok for us to reset our perks. Other than getting some bonuses on items, and leveling easier, It really wouldn't disrupt the balance.
BTW, I don't understand why some people are being jerks. I'm making a valid complaint, many others have the same complaint and opinion as this.
It's about character balance, not necessarily combat or gameplay balance.
