the quests are all the same, only thing different is who gives it to you.
bottom line is that at the end of the DLC Volkihar > Fort Dawnguard
Lmao. The vampire is known to have a glitch. Serana as your follower majorly weakens your Drain Life spell AND she's with you almost the entire quest. A minor glitch shows that when wearing any type of Thieves' Guild headgear, it glitches and doesn't show it but instead a bald spot.
The Dawnguard lets you get the Enhanced Dwarven Crossbow. In the end, you can still decide to be a Vampire, get this crossbow, AND not have Serana with you. Dawnguard all the way.
I picked vampire but I switched to an older save and picked Dawnguard after 4 hours. You're supposed to be stronger as a vamp but instead you're weak as a mudcrab.
The vampire lord form is kind of a FAIL too imo,by the time you change your companion already killed the enemy most of the time.
Also no looting as a VL and no entering doors,combine that with the terrible no stamina regen and you have a recipe for annoyance.
O.o really? In my experience VL is vastly overpowered if anything. Also you can enter doors with no issue, unless they're locked. It's true you can't loot, and you can get stuck in some doorways due to your size I guess.
The drain life you get is overpowered, but if Serana tags along she makes it really weak for some reason. There isn't any no stamina regen either. Unless you're in the sun. But that's because you're, you know, a vampire. The sun is bad for you.
