Things have changed since the Oblivion crisis and by people moving around. Argonians who haven't been anywhere near Black Marsh could've lost their poison immunity simply because of that.
Yeah and black people who live in america do not have sickle cells because they have not lived in Africa for 200+ years....sorry about the sarcasm, im a little annoyed and it is 2am here, but that amount of time would not effect a genealogical adaptation. Besides we do not know if Evolution really operates in TES the same as it does here. However what would explain that would be the Hist changing the Argos during the Oblivion crisis. But why would they make the Argonians more susceptible to poisons? Especially when they live in a poisonous environment and are about to invade another poisonous environement, Morrowind. I can understand reducing the poison resistance but to do away with it all together is ridiculous.
Why do the Redguards and Altmer suddenly have no disease immunity?
Why can't the Dunmer summon ancestor ghosts when Sul does it in the books AFTER the Red Year? The whole ancestor ghosts on fire thing is kind of BS when that is taken into account.
Cream of the crop has to be Redguards with destruction magic. Okay yeah they destroyed Yokuda supposedly but that was some kind of Sword magic that is more similar to the Thu'um power idea. So why do they suddenly have some magic when they have always been the distrustful pure warrior types?
There are many little 'eff you's to the lore in these racial bonuses, that is if they are truly complete and are not BS or misquoted. Kind of annoying tbh. I have doubts of the valididty and if it is from herp a derp then well maybe he or she misread it or something. Where is the list from btw? The 360 leaks?
