Both the Companions and College questlines were incredibly bad. Scores of dungeon crawler quests, almost no interesting characters, and somewhat bland rewards (except for that one thing the Companions give you, you know the one). College was the worst, however, for sure. Ancano was so obviously an evil guy that it really shouldn't be any kind of spoiler to anyone. Why not have him being actually good and the kindly old man being a dike in secret? At least it's going to be a little less cliche. Oh, and I am the Arch-Mage, yet I have to run errands for nobodies? What the hell is this? I should be negociating with Jarls and world leaders to expand the College's influence, or failing that threatren to summon a horde of Deadras in their cities if they dare to cross me. Yet I have to be a guinea pig in some girl's experiments and most rogues mages I find that outclass me by erecting instant barrier blocking any spell while pelting me with their own. But, if I resort to a weapon or just summon stuff it's auto-win. Way to make me feel like the top magic user in Skyrim.
Yeah, I ramble, but it's tough to sensibly play a mage in Skyrim. as Renegade says, it feels so empty and void, it's like no other character type was envisionned by Bethesda except either a stereotypical warrior hero (like that guy in the background), an hybrid mage/warrior, or a DB/Theives's Guild type with either daggers or bows,
and nothing else. Shame, because the Brotherhood and Theives questlines are really good. I strongly doubt the same people designed these 4.
