You didn´t address the main point of my previous post, btw.
Why does the dragonborn have to train with Vilkas? I guess it's a formality, to see if you really have any sort of skill to join them, or if you're all hype. Obviously it only takes one swing for him to realize you're the real deal. I suppose if you swung at him like a wuss, he'd say sorry, dragonborn or not you're not joining us with a swing like that.
Also, you become a spoiler because that's what the Circle does, and Aela is kind of grooming you behind Kodlak's back. She believes in the spoilers, and she passes that on to you. Dragonborn or not, they do have traditions in the Companions, and in order to join the Circle you had to be initiated. I'm sure the College has some initiation rites too.
Maybe the factions don't take into account that you're dragonborn. Maybe it just really is easy to advance in these places. Still, does Morrowind's approach really make much more sense? What if you did what you did for Kodlak and then you are told by Aela you don't have enough skill in one-handed to become Harbinger.
I'm not knocking Morrowind's system. It was good. I'm just saying Skyrim did it differently. To me, it's just different. A new approach.
And maybe the Companions fails as a guild, because it's not supposed to be a guild. In Morrowind, it made sense that by joining a guild (and it's important to realize Morrowind's guilds are very much real guilds. You paid dues to them, and performed guild duties in a formal fashion, and advanced very firm ranks, etc), you would have to progress up the ranks of the guilds to get to the top. But the Companions is not a fighters guild in the traditional sense, nor is the College of Winterhold. They are "factions", or groups, and the rules are really anything goes for them. Yes they have their traditions, and their positions of power, but it's not as set in stone as traditional guilds. Anyone can become "leader" of those groups just by doing the right things that others in the group may lack the skill, bravery, or cleverness to pull off. I see nothing wrong with that.
And if it so happens that you seem to be the chosen one of legend for these groups, I see nothing wrong with that either, given it makes sense in the lore and the writing. I can't speak for all the factions, but for the Companions, it certainly made sense and followed a very natural course. I'm not saying you get a free pass either for being the chosen one. Yes you appeared in Kodlak's dreams, but you still had to perform the actions. And like I said, actions speak louder than anything. You performed the heroic deeds, you gained favor, and eventually become the "leader".
I don't even agree that the Companions line was too short. I felt it was perfect. Like I said, I don't want to be killing Silver Hand by the millions just to puff out the content. The content was a good length, and "meaty" with some good twists and turns and events that took place.
So all in all, different from Morrowind, still as viable, still as good. Just different.
