I'm kinda disppointed with the lack of varitaion with questing too but am expecting this to be adressed with the DLC.
Lots of comments here about this being standard for RPG but the OOO mod for Oblivion shows it can be done. These were complicated quests which most of the time didn't get journal entries until you hit key points in the quest and most of the time you never knew you started until the pieces start to come together.
Here is a rough guide to one of the quests, Shadows in a Struggle for Power, that was posted on Filefront as there is no official guide to completing them.
As you can see the first journal entry doesn't happen until the 5th paragraph and it's scope is varied an story driven.
Shadows in a Struggle for Power
I'm not sure who Jephre is, but I know that he is "one with nature", leader of the Sylvan Rangers, and has recently experienced problems with corrupted followers of him. These Corrupted followers are searching for armor known as "Dread Armor", which, when the full set is worn, the wearer is said to be in contact with both the Netherworld and the real world.
In various Ayleid Ruins in the Gold Coast Southern Colovian Highlands, and western West Weald, you may have come across these Corrupted followers in braided armor and using braided weapons. You can't put on the armor, since you have to prove yourself worth to Jephre in the depths of Narind.
Narind is an OOO installed Ayleid ruin in the area in the Gold Coast east of Anvil, or in the western West Weald. I forgot which one, but it is most likely the first one. Deep in Narind, you will find a green stone. Take it and you will receive the power to summon the guardians of Jephre (animals like boars, wolves, bears) about 8 spells in all, the power to wear braided armor, and you will no longer be attacked by the animals of the wild. This includes Spriggans, you know, those women made of wood. And when you exit the ruin, the stone will turn into the "Spirit of the Wild" and run off in a certain direction. That direction is a hint. The wolf spirit is trying to lead you somewhere.
In the westernmost part of Cyrodill by the Abecean Sea, is an Ayleid ruin called Beldaburo. Right next door is another OOO installed ruin called Yeleri. Inside is the leader of the corrupted followers wearing 4/5 of the Dread Armor, minus the helmet. Kill him and take the Dread Armor. You now have the boots, greaves, gauntlets, and cuirass of the Dread Armor. So where's the helmet? It's in Fort Facian. Actually, I'm not sure. It's most likely that fort. If not, try these: Fort Sejanus, (probably not) Fort Cedrian, (good chance) Fort Flecia (good chance) Fort Entius (maybe). It's most likely Fort Facian, that should be your first stop.
Inside you'll find the helmet. Put it on, along with the other pieces, and you'll get a journal entry saying you feel like you're here, but then again your not. Notice how when you move, dark green clouds come off of the armor. How cool is that! But sometimes this will stop if you enter or exit something. Just take a piece of the armor of and put it back on to get it going again.
Now that you have the full set of Dread Armor, (there's no shield) head into the upper part of Cyrodiil where all the snow is. I forgot exactly where it was, but somewhere up there is an Ayleid ruin that you can't enter unless you are wearing the full set of Dread Armor. This Ayleid ruin is, on the outside, just a stone door. It has nothing on the outside. The door is on the side of a mountain, so search snow covered mountains.
When you find it, put on the full set of Dread Armor and enter. Inside are spectral warriors and a boss. This boss has a weapon that you can only wield while wearing the full set of Dread Armor. This goes the same for the ghostly weapons the spectral warriors use. The boss has a sword called Icxth or something like that. It's an enchanted weapon from the Netherworld that has an infinite charge. The ghostly weapons the spectral warriors uses have an infinite charge like Light of Dawn, but they do 1pt of frost on strike instead of shock like Light of Dawn does.
When you have Icxth or any other ghostly weapon in your inventory and you unequip your Dread Armor, those weapons will be removed too since they require the Dread Armor in order for you to use them. In some other Ayleid ruin in eastern Cyrodiil is some mage that has been searching for the Dread Armor. In the room where you find him is a note describing his search for the Dread Armor. Finding this mage is optional though.
