Yes, people seem to forget that the Thalmor do not want any victors in the civil war, Stormcloaks or Empire.
interesting, i never saw this. you know what would make the choice more immersible is if the quest line was inverted depending on the side you pick. for example there is a quest where you have to fight to get the jagged crown why cant one side be defending while the other attacking and depending on what side you have chosen would be what your doing attacking or defending that would make it more interesting but that's a bit off topic anyway
on topic:
it really doesn't matter. and its pointless to defend either of them its an opinion and no one will change there opinion easily... its difficult to argue on these matters so im done trying all i will say is my opinion stands with the empire and leave it at that
