Many Elder Scrolls vets treat the first character in a new game as a likely throwaway. Our goal isn't and never was to rush pell-mell through the entire game, right out of the gate, be done with it in 20 hours and go on to something else, but to experiment and think and try to figure out how the game works. Yes - some of us actually enjoy that.
I'm ambivalent about the removal of classes. Personally, I don't much care - the "classes" that I use in past games don't have much to do with the actual character and have more to do with working around the inevitable idiosyncrasies of the game. However, for just that reason, I'm a bit wary. In the past, I could compensate for the failures of the game by manipulating builds. Since I no longer will have that ability, and since the game is sure to have poor design decisions (If it doesn't, it'll be the first TES game in history not to, and I just don't count that as particularly likely), I'm concerned that I'm simply not going to have any way to get around the game's inevitable flaws.
That and I honestly appreciate any mechanic in the game that discourages those who desire instant gratification and guaranteed success. If such people get frustrated and give up on the game, then, sincerely - good riddance.
I wouldn't call choosing your skillset as you level "instant gratification and guaranteed success." If anything the previews seem to indicate that Skyrim will be a bit more difficult than prior games.
Anyways, I have to disagree with you on the class issue. It wasn't that your first character was a throwaway, it's that the first dozen or so were. I nearly gave up on Morrowind when it first came out because after a warrior who got killed by a Nord, a mage who got killed by a Nord, a mage/thief that got killed by a Nord, etc. I eventually figured out that I should skip the Nord and just go to Balmora, where I stayed true to my class (pure thief) by stealing absolutely everything that wasn't nailed down, making it so that after an hour of play I never needed to worry about money ever again.
And the funny thing is, by the time I beat the game, I was decked out mostly in heavy armor and using a sword instead of a dagger. After a certain point it didn't matter the least [censored] bit what class you chose at the start of the game, and towards the end all the characters sort of became the same jack-of-all-trades demigods. If that's the end result then why do we have classes to begin with?
Also: With the new system, people will
still abandon their first few characters when they figure out they don't like playing an orc, or that maybe taking those Frost spell perks was the wrong move for their style of play. The new system will just lessen this phenomenon's frequency.
