Ah I see this thread has come again.
Personally I like the Nords, and I liked Tiber Septim(I never heard "Talos" until Skyrim. In Morrowind and Oblivion all I heard was Tiber Septim did I miss something?). To see them oppressed by not being allowed to worship Talos, AKA Tiber Septim the guy who founded the freakin empire, being hounded by snooty, conniving, conceded, High-Elf bastards that round people up and torture them, lied to, its just too forgive.
You cant just tell them not to worship their God-hero they've idolized and known countless centuries! Who was supposed to be your God too. Ive heard "By the Nine's" so many times when ever some Elf or some uppity lord says "By the eight" I wanna draw my mace and knock the teeth out their mouth!
If it was just that I'd still be 100% for Ulfric(who got screwed big time by the Empire), but its clear the Empire is weakening and their damn near letting the Thalmor in the backdoor. The Imperials of Cyridol clearly dont mind the Thalmor busting Skyrim's chops as long as they arnt bothered. Skyrim will be just fine on its own thank you very much.
I dont think any one would willing(or intelligently) send in army into a land plagued by Dragons, and thats guarded by The Mighty Dovakin, So bring em on! In fact the next DLC should be a mini-conflict between the Aldermeri Dominion and Skyrim, so that I can show them just what a God really is.
