I understand what you're saying, and mostly agree, however, Elder Scrolls has taken a turn from fantasy game to Dungeons and Dragons with this latest game. I would have preferred to never see that happen. There is no excuse for putting dragons in a TES game (in my mind).
Yannow, I had a split-second reaction when I saw the trailer, one that was "ahh [censored], they actually are doing dragons?"
And then, once I had the opportunity to consider things, it went away.
The dragons potentially represent, at their weirdest lore-conception, the servants of Aka, leser Aedric time-spirits, Jills, who come in and mend time when it's about to be. or has been, screwed with. Or who assist Time in fitting the entire world in its gullet.
And let's face it, there have been dragons in this game series for quite a while: Nafalagahoweveryoupronounceit from Redguard, Tosh Raka from Akavir, the Cyrodiilic understanding of Dragons as rare and hidden and sacred to the Empire, the river-dragons from the First Pocket Guide to the Empire, and of course the Dragon God of Time, whose choice appearance is not just a coincidence for this title.
[And note, even if there are those who peruse this thread that happen to disagree with these arguable interpretations, the point still remains that the Dragons of TES are more than just cliche Dragons.]As for the DnD comment, it seems extremely premature, given the amount of information we've been given versus the entirety of the game we have yet to see.
EDIT: Which, by the way, the info we've been given indicates that they are keeping what worked from Oblivion/FO3, while returning to a Morrowind/Redguard style of world-building and storytelling. Which is something that I am extremely excited to see.
