That's what I thought too when I read about the dragons being farmed for their souls, but I think they will not be as boring as the Oblivion gates, because:
1) It can't take
that long to kill a dragon
2) Unlike the gates, dragons are roaming freely in the game world, which means every encounter may be different because of so many parameters: where the fight takes place, how can you use the environment to defeat the dragon, nearby npcs may be involved, you could have companions for some of the fights, you can have the "luck" to lure more than one dragon in the fight (how cool would be a dragon vs dragon while you're watching
), and most important, the
level scaling is changed, so the intensity and difficulty of dragon battles should vary according to your level and gear from very hard to easy, unlike the gates.
