Because starting a new character is part of an RPG. You see what you missed when you choose what you did. I've started countless new characters in DA: O, ME, and Skyrim, and I can say a new character is often a refreshing change of pace.
1) People should know whether a perk is bugged or not. Finding out it only a quick Google search away
2) Everyone has large amounts of saves anyway, because of the numerous bugs not including perks
3) If a perk if vague, again, they should know. Google is a fantastic tool for an RPG player.
Lastly, I've had a great attachment to many characters. But starting a new game doesn't mean that character goes away. And AS IVE STATED PREVIOUSLY, you can misplace way more than a few perks, up to 10 or 20.
Sometimes it is, but with Skyrim? Not so much, especially when your choices do not effect the game
at all. "hurray i finished the civil war quest! *people act as if nothing has happened or anything ever transpired*...."
That right there is a defining action and important aspect of RPGS, Skyrim lacks it..... Badly.
Anywho:
1) Not everyone has access to a PC or the internet.
2) You can be suprised, i have seen quite a few threads on here where people overwrote their main save file due to only having a couple, or having to restart due to a bug and they had no other saves.
3) See 1, but yes, those who can will use it, honestly though i did not know that such a thing even existed until about 3-4 days ago.
True, maybe even 30 depending on what archetype you are going for, but lvling 60+ slows down quite a bit, especially since you are forced to level skills that are not related to your characters archetype.
@Vaen
You sure are determined to keep this argument going aren't you?

I don't think I can stand a 3rd night of arguing the same things over and over. I don't think this particular request will happen, definitely not for Skyrim, but what is the point in arguing about it, Bethesda is going to do whatever they want, and that is increasingly, anything that sells more units. Good luck with the argument.

Who says i am arguing?

you seem to be missing the point of this thread, especially since i never once said i demand it in the game, simply asking the question why you feel it will harm your experience when it is a single player rpg, where another persons choice does not effect your game.
