I really don't want to see any focus on either of these ... creatures.
Vamps are basically (and always have been) unplayable in TES games. Sure you could be one ... but then what? At least MW had some Vampire clans you could join.
WereWolves in Skyrim is a joke. Even with the totems the form is a waste and is really against the games own lore about WW. Again MW (BM) did it right, treating it like a curse. Even with a WW perk tree and adding powers I just really have no desire to play as one when I can play so much better as a human (and walk around town without being attacked). Again just pointless.
I agree,right now there is no real reason to play as either werewolf or vampire..maybe if you want to RP something but other than that,no

I really hope they make the skill tree...But if they make one,they should also make the werebears and make a skill tree that covers all shapeshifters
Werewolves need to do more damage on higher levels and they need some kind of basic armor rating...or armor perk that you could increase.
The fear howl becomes useless too above level 30,becouse many creatures and NPC's will be level 25 and above and it only works up to level 25.So they should improve it a little...maybe up to level 35.Aura or scent abilities would be nice and not like in a totem form as we already have.
