The only reason I would bother with killing dragons is because:
1. It's bad for my own personal gain if there's no one left for me to kill or pillage.
2. It's bad for my own personal gain if I'm dead.
3. The game does not allow me to make deals with dragons;
Spoiler
who knows...maybe I could have made a deal with you know who.
Otherwise, I would just let the dragons fly around killing whoever they wanted, because I simply don't care about any of these people. If I want to play this kind of character, it seems as though I have to skip the main quest entirely and do everything else before triggering the dragon events. The Brotherhood for example, likes to be "known" yet remain entirely in the shadows and not have any specific member actually known to the general public. If I wanted to be part of the Brotherhood, yet was going around "saving the day" from all of these dragon attacks, you would think I'd be pretty damn popular. Even if I didn't go around announcing that I was a member of the Brotherhood, eventually the people I was contracted to work with would realize who I was and the word would spread.
I'm not really complaining per se (I'm really not), but does anyone else find this an odd removal of choice? If my very first character had been this kind of person, not much of it would make much sense. Besides that, the game never seems to make anything seem urgent. I mean, instead of going around killing dragons, and preventing you know who from doing you know what, I'm happily ignoring that and leveling from 1-50+. I mean really, how long do you realistically think it would take someone to go from novice to master? Years and years, not a matter of days.
