Did you?
Spoiler taken straight from the dossier "A Stormcloak victory is also to be avoided, however, so even indirect aid to the Stormcloaks must be carefully managed."
Ah, touche mate. I guess I didn't remember it correctly, read it a while back, thanks. Still though, my point stands, a united Empire > a divided one. Against the Thalmor anyway.
I'd support the Empire, many people in game say how Skyrim needs the support the Empire provides. Although it is falling apart, it could have regrouped and got stronger if not for the Stormcloaks starting a civil war. All they want is to worship Talos, and the Empire seems to want to do that to, they just can't due to the Thalmor.
When you finish with the empire side Tullius even says how he doesn't think the peace with the Thalmor will last for long.
Could you imagine how if instead of fighting the Empire the Stormcloaks sided with them?
They would be able to fight back the Thalmor and everyone would win.
Precisely. The Empire didn't want to banish the worship of Talos, they did it so their entire Empire wasn't destroyed. Once the Thalmor are taken care of and the worship of Talos is no longer banned, they'd have no need of Stormcloaks, would they? Besides the Skyrim for the nords bit which I think is a tad racist.
