You chose not to read the rest of that post I see
You are NOT a DRAGON, you may have DRAGON BLOOD in your veins but I highly doubt we will be growing wings any time soon and flying away.....There is not reason for Beth to do this ingame at all anyways, you were called many titles in past TES games that said you were not able to catch any type of disease YET you still were able to.
Besides...I like my hero to be a little tainted
"Of course Bethseda may pull some common lore breaking in attempt to better serve the player base." Was in my original post. they'll break the lore for the players, they've done it before and will probably do it again but it's still lore breaking and I don't particularly care for it. Which is why I'd rather have the character immune to them, allowing it to be modded in later, perhaps add magical rings like Hircine's Ring from morrowind.
That's an assumption. For all we know, it could have metaphorical (non-physical) conotations. St. Alessia, Reman Cyrodiil, and Tiber Septim are all (presumably) Dragonborn too, yet there's no evidence of them being actual dragons.
Well, Uriel Septim VII was supposed to be a direct descendant of Tiber Septim, and I believe anyone who finished Oblivion remembers the final scene and what happened to Martin Septim, Uriel's son. So by this tracing lineage back... I believe you get the point.
