dont read this if you havent gone through the dark brotherhood questline.
anyways, im going to start a new character with more immersion and thats focused on creating a story of that character; an rpg. so in every playthrough of skyrim, i have either not gotten around to it, or i went through the darkbrotherhood questline, because besides their stupid looking armor, they are awesome! but this time, i was thinking of shying away from them and the other guilds and focusing on dawnguard and dragonborn. so what are the pros and cons of destroying them? so far i know of:
cons - the katariah wont appear in game, meaning you cant get the windshear. hmm... lol i actually think thats it, besides not getting to upgrade it and get those benefits.
pros - you can get all the armor of the people, the blade of woe, even though i think its crappy. a dagger that swings at the speed of a sword. did they ever fix that? you also get the unique hammerfell garb and the red redguard hood, which i think is really interesting. im also planning on supporting the imperials so that would look like an amazing armor combination.
so yeah, are there any other cons i should know about regarding destroying them?
and another side question, since i dont plan on doing the main storyline and wont learn shouts or kill dragons, my character wont discover hes dragonborn, so does that mean i can or cant do dragonborn's questline?
