I like the dragons. I'm quite impressed by their AI, being that they're massive creatures that aren't set encounters, that there's no predefined (crash-)landing spots for them (which does make it look a little funny at times, but nothing's perfect), no predefined flight or attack patterns, etc. They can do what they want how they want when they want, just like any other NPC. It's always fun to watch one engage in battle with something to see what they'll do.
Makes it less fun, IMO. Feeding on people's blood is like a quintessential ability for vampires, but doing that in Oblivion or Skyrim strips you of your stronger vampiric powers. Why would I become a vampire if I'm encouraged to not act as a vampire?
They should be, since the biggest group of werewolf hunters use silver exclusively, and they did in previous games IIRC. Whether the game actually has silver weapons do more damage to werewolves (as opposed to just undead), or if it's just "for show", I don't know, but silver weapons on the whole were poorly represented in Skyrim. There's no silver weapons or armor besides one- and two-handed swords... no axes, no hammers, no daggers, no arrows, no bows... and they're only in possession of the Silver Hand. You can't even craft or improve what silver weapons there are despite silver ingots being plentiful.
Again I think things will be fixed over time.

I like to remain optimistic because i believe a positive outlook creates positive effects, but then

I'm a wishful thinker.
Sadly again Skyrim being my first Elder Scrolls game, I really can't give much to comment about via lore, or how things were done previously since i'm a technical novice who just thinks how things should be.
As for the Silver weaponry I wasn't overly bothered about it since Steel is better and comes rather quick, as quick as Iron really. But only recently use Steel after I use Iron for a while, but as I previously stated I only just started with Skyrim.
According to the Werewolf perk. I think overall damage resistance would be better. Since silver doesn't REALLY seem to affect it all that much more than Steel, if not less. And also since I stated before weapons like Glass alone REALLY tear through Werewolves regardless of how much health they have.
But again. I'm optimistic things will be fixed over the course of time, I mean hell they said they'd give us DLC and we haven't got that yet. So they will still probabily be adding things and fixing things. So yeah

I'm feeling pretty good about all this.
