I was never implying that YOU would but other people will

The vampires did not really defy lore as nothing in books or lore said they cannot do what they do in skyrim, and they not the wrongs ones, they are the volkihar just with a backwards feeding system that is very unwanted, and "very unwanted" is an understatement.
but lets get back on topic.
The feeding system may be a lore breaker yes and I strongly think this should be changed. However it is up to bethesda but if they have any sense or care not only for the fans but the lore then they would have fixed this ages ago, they still could you know. We are all waiting for it and we are not going to shut up until we get it.
This will make vampirism much more interesting and "true" to vampire behavior. Right now, it encourages laziness as all you have to do is nothing to be powerful, unacceptable. We should have to feed to get stronger and to maintain it. Feeding often will make it more "realistic" for lack of a better word and would change the way you play the game as todd once said about vampirism.

Bethesda did vampires horribly. It's simple as that. The current vampires break the lore. It's true that Bethesda can change it up as much as they want, but not without pissing off a lot of fans. I already am not buying their next game (at least not right away) since they come out bugged as all hell. I don't accept that from a developer, so i'll show it by not buying their products. Breaking the lore all the time would just be another reason to not stick with Bethesda.

On topic though, the OP suggest a lot of improvements, and a much better design than the one Bethesda currently has.

No frost abilities...INSTANT wrong

I can agree with this vampires in skyrim should have an innate frost spell like an ice cloak spell that would be good. This is the reason why my vampire characters specialize in ice magic.

True though there is frost resistance but that is not much but very useful against frost dragons.
But I have already said "vampiric frost breath" a few posts back in a list of things that could be done.

I'm going to have to disagree with this. As the game currently stands there is not one true Volkihar vampire. They are all Cyrodilic vampires.

Then we will have to agree to disagree, I guess castle volkihar does not exist then right? or even volkihar master vampires not to mention volkihar vampires, I guess it is just our imagination. They are all volkihar, simple and end of story. devs would not put the word "volkihar" in the game if it had no meaning to the vampires.

They Screwed the lore, that is why they are called Volkihar in-game but dont fit the lore

That'd be cool too, probably better, actually. And maybe a change in appearance as you get more powerful. Same for VL's.

Snow werewolf for nords would be epic!

I want a Lycan with some Pauldrons...dont know why but i want it

I would like to have the chance to either get the bat-like face or the cape and crown for the vampire lord.

Nothing in book or lore says a volkihar cannot act the way they do in skyrim but again I say I agree that the feeding system should be changed and fast.

Drake Malice is right. You can't go by Dawnguard, because Dawnguard goes against the lore. They're called Volkihar, but they aren't truly Volkihar.

Bat face would be cool. But, you would need some power to go with the new look. VL is powerful, but normal vamp form is trash.

I take the devs side over a fan belief any day, they don't put "volkihar" in for nothing, they are the volkihar, Just because they don't act like what you expected does not mean they are not. Simple and end of discussion.
Now let us get back on topic shall we?
Ideas on how vampires and werewolves can be improved. I gave mine a few posts or pages back.

yes, normal form is trash, which is why we want an improvement on feeding, physical powers and frost magic bonuses.

They get resistance to frost. Not perfect but something, right? Question. Did vamps get resistances to frost in Oblivion?

Well, there's armored trolls, maybe the dawnguard could hook us up!

Already said my points but I will say it again.
Vampires.
pros.
Vampiric Strength = Unarmed damage, one/two handed damage with X chance to stagger or knock back opponent.
Vampiric Agility = Faster sprinting, slower stamina drain at night, higher and longer jumping.
Mist form for human form.
Vampiric frost breath.
Improved feeding system.
bonuses to frost magic. (either less mana cost or better damage)

Cons.
Weakness while in divine temples.
Unable to use silver or blessed weapons (turn undead enchantment)
Unable to get blessings from divine shrines.
Unable to get well rested except from a coffin.
Need to feed often to get stronger and maintain powers.

Optional.
Bat-face vampire look for the player (perhaps as a stage four thing) or as a lesser power similar to Vampire lord, you do not transform but your face changes and you sharp pointed nails but are still able use weapons and clothes (unarmed damage is enhanced further)


Lycanthropy.
Pros
Werewolf Packs.
more hircine missions.
Werebears.
Wereboars.
Ring of Hiricine gives unlimited transformations.(apparently this already in)
Wolves will not attack you in either beast form or human form.

Cons.
Silver does more damage (if it doesn't already)
Unable to use silver weapons.
Forced monthly transformations (upside is you are stronger and tougher and no longer need to constantly feed during this transformation as it is the "natural" time for it.
Werewolf hunters.
Wolfsbane and weapons coated with the poison does tremendous damage.

I kind of agree with this. Although they dont reach through ice and have an ice castle, or ice breath, they do have frost resistance, which is close enough for me. Would be cool if they did these things, but whatever. I was kind of expecting something like this in the forgotten vale, but dragons trump vamps to me any day.

The devs contradict themselves. The in game books are different from what is actually put in. I'm betting the reason they put Volkihar in is because they are supposed to be the strongest clan, so they named higher level vamps Volkihar.

In my opinion, either the current vamps need to go, or the in game books talking about vamps need to go (which means changing the lore). The in game books currently contradict what is actually in game.

They should have added a vampiric ice breath but reaching through the ice perhaps would have been a complicated game mechanic, maybe VL's mist form is an explanation on how they do it.
Some do dwell in icy areas, ice caves and other underground areas etc.

They put them in to fit with the Skyrim specific name but they were to lazy to make a new system for the vamps, They are the Order in skyrim stealing the name of Volkihar, it is obvious so take off the Beth-is-Righteous goggles and look again

I kinda agree with mort on this yes the volk vampires are not what we expected given the information in the books but they are still volk vampires thats why bethesda gave them that name. Do I like it? No I don't but just because I don't like it does not mean that they are not volk vampires. There are things bethesda could improve with them as mort suggested but they are still volk vampires.
