agree, I hated all the Dwemer ruins tbh
Dwemer ruins have several things going against them:
1. They are typically chock-full of Falmer, Chauras, Dwarven Spheres, and similar very tough enemies. Your best course of action, particularly if you're not a mage character (and particularly if you've been ignoring the restoration perk tree), is to spend a month in-game stocking up on potions, and Talos forbid you're playing under any sort of restrictions regarding HUD visibility or potion usage.
2. Dwarven machine enemies seldom drop any sort of useful loot, especially if you're a light-armor user, have passed dwarven armor in the heavy-armor smithing tree, or aren't doing blacksmithing very much at all. Not to mention that dwemer gear is
heavy.
3. Particularly if you have to go to Blackreach, like, say, in the main storyline, they are
abominably long. The only thing Alftand Glacial Ruins has going for it is that it has an escape route halfway through. It can take over an hour of real time, even at low difficulty levels, and that's assuming you
know what you're doing.
4. Imagine you're a first-time player. You've just finished Blackreach, are likely completely out of healing potions, fast-travel to the Throat of the World not expecting anything but a cool cutscene of you reading the Elder Scroll to happen, and then... Surprise! You have to fight Alduin!
I just did that part of the main questline in my current game. In Sjadbek's game, and likely in
every subsequent game in which I play the main quest (unless observing some sort of restriction), I used/will use the "wooden plate" glitch employed by speedrunners to get straight into the Tower of Mzark from Skyrim itself, while praying I don't ever update a patch that fixes it.
Tl;dr Dwemer ruins are torture chambers for both the character and the player.
