I think it's quite BS. There is no proper balance at all on choosing sides, the Dawnguard is obviously the clear winner, and Bethesda was quite bias towards them, it's BLATANTLY obvious. If it wasn't for Roleplaying, there would be absolutely NO reason to choose the Vampire side. I'll just quote what I posted on another thread, listing the perks/benefits/rewards of each side:
You guys are giving terrible examples, stop being so hard on him. This truely is an outrage.
Vampire Side Perks:
1) Vampire Lord
2) Blood Potions (Useless because nobody attacks at Stage 4 anymore.)
3) Death Hounds (equivalent of Huskies)
4) Vampire Lord Artifacts (Amulet/Ring that boost your powers slightly as a VL. I'd say this is equivalent to the Dawnguard's Crossbow Upgrades.)
5) 1 Unique Restoration Spell
Dawnguard Side Perks:
1) Vampire Lord (That's right, they BOTH get it.)
2) Ability to Smith and Purchase every Crossbow and Bolt type...something the Vampires can't do even for regular Steel Bolts
3) Armored Trolls
4) Huskies (equivalent to Death Hounds)
5) 5 or so Followers
6) Crossbow Upgrades to Enhanced Cross, Dwarven Crossbow, Enhanced Dwarven Crossbow, Steel/Dwarven Bolts of Exploding Frost/Fire/Shock. (Equivalent to Vampire Lord upgrades, I'd say.)
7) Runed Shield and Warhammer
8) 3 Unique Restoration Spells
Hell, both sides even get to blot out the sun. So let's see here...it looks like Bethesda was quite biased towards the Dawnguard, or is it just my imagination?
So wait, we're not allowed to complain that Vampires don't have a practical way of obtaining Ammo for our non-upgraded Crossbows? By that logic, the Dawnguard shouldn't be able to turn into Vampire Lords or blot out the sun.....OH WAIT.
Yeah, it is quite messed up, indeed.
I'm not asking for Vampires to be able to upgrade their crossbows or bolts....but we should be able to, at the VERY LEAST, craft simple Steel Bolts. It is a new weapon for goodness sakes that was the one of the MAIN FLAGSHIP FEATURES of the DLC. Dawnguard side gets Vampire Lords without the artifact upgrades...so why can't Vampires be able to craft bolts without the upgrades? It's only fair.
Again,
BLATANTLY OBVIOUS that Bethesda was very biased towards making the Dawnguard more desirable.
