I'll look for more of your posts, maybe on the lore forums, because they're alleviating my concerns. But I still can't shake the feeling of these alliances feeling completely forced just so that the game can have factions.
How about Argonians and Dunmer teaming up? Can you put my fears to rest there too?

Don't the Argonians hate the Dunmer, especially in this time frame, for the Dunmer forcing their people into slavery?
Yes, but the Argonians must always be viewed in conjunction with the Hist.
There is good evidence that the Hist calls the shots when it comes to long term goals and politics and they are, well, sentient trees that share a hivemind.
They are unknowable, alien and we cannot comprehend them.
As has been pointed out by another poster on the forum somewhere, the Argonian slaves that we see in third era Morrowind sometimes come from raids on the edges of Black Marsh, but more often are sold into slavery by the Argonians themselves.
A possibility is that for the Hist an individual Argonian is simply not that important, in the same way that one cell of your hand is not important to you, they are a hivemind do they even understand the concept of individuality?
They may trade slaves with Morrowind in order to realise some short term goal, placate the powerful neighbour and at the same time already realise that in the long term their machinations or fate will ensure that they get everything back they handed over and then some.
Remember that when Red Mountain erupted after the Oblivion crisis the Argonians took back all of the territory lost over the years to Morrowind and exacted a psychological victory on the Dunmer that will be felt for centuries to come.
I believe that the events of the MMO, Tamriel being svcked into coldharbour, may be a reason for the Hist to turn to the living gods of Morrowind for protection against something they themselves cannot handle as well.
Ill msg you what I wrote on the Ebonheart alliance as I dont want to keep reposting the same stuff
