Exactly. This is why the Elder Scrolls games are going downhill, and it is beyond the whole Lycanthropy/vampirism issue. But in regards to vampires, this all started with Morrowind. Noticed your character in Morrowind could barely talk to anyone if a vampire, which made quests difficult to complete. Even ingame dialogue says no vampire could blend in, because they are so hideous. People complained about the sun damage, about the difficulty in completing quests. Of course, this was fixed in Oblivion where the vampiric player could blend in if he fed(and dialogue talking about Cyrodiilic vampires actually exists in Morrowind, too! And even foreshadows about Janus Hassildor and the rest). Sun damaged only happened if the player fed on a person as well, giving him 24 hours to walk around unharmed by the sun. To stay in that stage, all the player had to do was avoid sleeping/resting and his vampirism wouldn't progress.
Yet people complained about vampirism in Oblivion:
"Why do we have to feed on people, Bethesda! It is so hard! I can't even find a sleeping person, even if there are beggars in ever damn street corner!" or "why do resist talking to me when I look like a fugly pale monster? Even if I have Vampire's Seduction to boost their disposition toward me, or feed on beggars just down the street corner, this game is too hard! Vampire gameplay svcks!"
Then Skyrim came out. Notice we don't burn in the sun as we did in Oblivion. We don't risk roasting to our deaths. Our stats are merely depleted. We also didn't get significant boons as we did in Oblivion. Feeding was the same, and the mechanics were the same, yet people attacked you this time around in stage 4, as opposed to only guards in Oblivion attacking you for being a vampire.
People cried out to Bethesda, whining why their game is so hard and why villagers were attacking them. Then Dawnguard came out . . . and let me not get started on this.
Oblivion vampirism: Great powers, but also kinda severe weaknesses.
Skyrim vampirism: Laughable powers, the weakness being a Daggerfall simulator. That, and level 4 hostility.
Dawnguard vampirism: Now you can transform into a third person monster that has nothing to do with your character! Oh, and level 4 hostility is gone.
TES VI vampirism: One level. +10 Frost Resistance, -10 Fire Resistance. No hostility or weakness to the sun, ever. Feeding exists only for the "Bloodsvcker" achievement.
