I'll be the first to admit I'm a victim of rather high standards. As soon as things seem un-loreworthy they tend to get kicked to the curb, there's enough "stuff" to talk about on Tamriel and Nirn that we don't need people making less-than-subtle inserts of Warcraft lore.
I appreciate any man, woman, or it that makes a quest mod, but calling them on par with an official DLC at this stage is laughable at best - such is the basis of my argument.
Then just look around. There are plenty of people who like yourself will not install a mod unless it's utterly lore friendly and as such there are a myriad of mods suited to those people. I too, will not install a mod unless it's lore friendly.
I don't think anybody made an argument that suggested quest mods were on par with official DLC, which is of course, not to say that user created quests are bad; i've played several fully voiced user created quests that are more fun than some of the quests in the main game, and i currently have a mod installed that adds 50 fully voiced NPC's to the game (and few thousand lines of dialogue) who are more interesting and well thought out than pretty much all of the vanilla NPC's. The person you responded to suggested individual mods were worth more which is hyperbole to say the least, but to put it bluntly, I have enough mods installed to equal that of the content included in Dawnguard, and best off all, it's free.
