I SUPPORT THE [censored] OUT OF THIS THREAD 
Seriously though...I've been advocating a pirates DLC since I came here; yet all I see people was like: "Hippie Valenwood DLC... Orsinium DLC that I really wouldn't give a skeever's ass about...a Thalmor DLC that start yet another boring war that couldn't we POSSIBLY let ES VI takes it? etc, etc..."
Though Dwemer sounds interesting, but I would rather have something fun; to live it up a little, satisfy the raiding and pillaging urges and/or extensive treasure hunting urges. No lore dictated the Dragonborn has to be a good guy. Let us hook up with bandits and make money. Fight octopuses and giant mudcrabs. Let Skyrim tremble at the sights of the [User Generated] Marauder!!!
We have vampires, but no zombies in sight... logically I would like to have pirates!
Put the Sea of Ghost to good use! All that depth just can't be for nothing! It can or can't be tied to a new College of Winterhold arc or a Thieves' Guild arc; it really doesn't matter to me. You could raid Thalmor ships if you all are that longing to stab a Thalmor.
