But it has nothing for me, for me anyway.
I could care less about Auriel's bow, I'm a mage I'm never going to use it.
I'm a mage and I'm not being a vampire so I joined the Dawnguard.
Funny thing is, you get super awesome dragonbone weapons, and armour and crossbows. You also get a few measly spells that only hurt vampires, and a few conjuration spells. No new mage clothes or any updates to magic really.
Dawnguard is great, just not for me, honestly not for any mage looking for anything special.
Auriel's bow, crossbows...its good for archers though.
Not complainin' just sayin'.
