Some are shorter than others, but alot of people just try and rush them them, instead of truly enjoying them.

Really.
1: Explore a cave
How much time should it take?
I'm not a thief, and thus I don't open locked chests.
I'm not a looter, and thus I don't pilifer graves.
2: Retrieve some books
Once again.
How can it take more time than it takes to actually explore the cave and pick up the items?
3: Explore a cave
4: Explore another cave with a harder boss
5: Things get rough
6: You're now the leader of the organization
I count 6 quests in total.
Compare that to oblivion, where there were SEVEN MAGE GUILD DEPARTMENTS.
Oblivion had as more mage-guild departments as the Skyrim college has real quests.
...
Ranks in oblivion:
Associate
Apprentice
Journeyman
Evoker
Conjurer
Magician
Warlock
Wizard
Master Wizard
Arch-Mage
That's more mage guild ranks than there are college mages!!!
You had to do SEVEN quests before you could become an APPRENTICE.
How many proper quests are there in total for the mage guild in Skyrim?
...
Would it hurt to take one barmaid's quest and just add it to the mage guild, so that you could reach a higher rank than apprentice before you became archmage?
