Don't criticise Oblivion for making mistakes and then not doing the same when Morrowind also changed the lore.
No, Daggerfall changed the lore in this situation and yes, I do wish they had not but stop blaming Morrowind. They are exactly the same as they were in Arena and if thats the case, Oblivion is at fault for this too since it used the Dunmer with blue skin. Also, I have full right about complaining about Oblivion's changing of Cyrodil.
A better option would be to see just how much we do know about the Mythic Dawn, but fine.
Feel free. Here the main things I got about them from Oblivion.
1) They worship Mehrune's Dagon.
2) They appear to hate the empire.
3) Their leader, Mankar Camoran seems to Believe that Nirn (Or is that every realm) belongs to Mehrunes Dagon
4) When they die they go to "Paradise"
5) They are responsible for opening the Oblivion gates and succeeded in getting Dagon into Cyrodil for a few minutes until he was sent back into Cyrodil
There are a few details about their leader and how they get new recruits which are interesting and confusing so I wish the game expand on those as well as everything else. I mean, why a Bosmer? Why not get someone else to join you and how will you explain your plans to destroy the empire to them without driving them away? They could have given us much more info.
What? I specifically mentioned Morrowind. And the point was that you cannot change someone's perception. The vast majority of Morrowind fans probably consider that just another fantasy medieval RPG, and don't pay any attention to the lore of the game. It has nothing to do with how the main quest is written.
That's their choice then but the main quest can't be broken down to Good Empire vs. Bad Rebels. The simplest it could be (Even with removing tons of details that make it unique or more unique then Oblivion's poorly written MQ) is Nerevarine vs. Evil Dagoth Ur and this is losing all the details about the Tribunal, empire's small involvement, and Azura as well as much more.
And I'll reply to the rest later, I need to go and find Mythic Dawn info. Someone's gonna ask
Reply when you feel like also, if you could show me some of your sources for the Mythic Dawn info I would be thankful. Personally though, when it comes to the lore, at least for me, more detail would be better but don't make that one source tell you everything or make it be 100% fact either. Speculation is important but according to you Gallowglass all the lore is speculation which is way too much for me.
Quick Edit: I found the UESP lore article on the Mythic Dawn. It doesn't contain much info. Neither does the Oblivion Article.
