This. IMO, magic would be something that takes a lot of time and effort to learn, moreso than swinging a sword or sneaking about.
Whilst i agree with you in principle, i think you and others are forgetting one major thing - it's an RP game.
It's just as plausible playing as a master wizard or whatever straight off the bat as it is playing as an apprentice mage. The game doesn't kick off from birth ala FO3, it begins with your character being an advlt. And the fact there's grey hair, a complexion slider etc, it's easy enough to start your character at any age.
if people can ignore helgen and the MQ, then others can ignore the need to spam spells as to reach a certain proficiency then begin playing from a certain level.
