I find random high level stuff the everything else is really weak? Anyone know why? Also, My weapons kill everything really quick, but I'm playing on novice, just because I like to be invincible with crappy equipment.

you shoudlnt expect lowly bandits in full glass armor
youll find harder opponents, you just have to know where to look for them. and in a small iron mine is not the place (try dwemer ruins theyre always a hoot)

Because if they could afford ebony weapons they wouldn't be bandits.

I've always wondered why the marauders in Oblivion lived in those crappy old castle ruins when they could have just sold all their equipment and bought the nicest manor in Anvil.

Walk into some Dwarven ruins or something

Before the game was released, the devs said that once you enter a dungeon, the dungeon level range will be "locked".

For example, you clear your first dungeon. You were level 5. So the dungeon will be locked in the level 5 to level 10 range.

If you come back at level 28, they will be at most level 10 with their appropriate gear.

Find new dungeons.

Bandits with glass and daedric equipment was stupid in TES4. There were many mods aimed at fixing that. IMO the "leveled loot" is still too aggressive, because merchants start selling all the high-level stuff once you're at a sufficient level; that kind of loot should only be had through smithing or delving through extremely vicious dungeons, not plonking down a bit of coin to pick from a rack. Glass and ebony are supposed to be so rare that only the very wealthy can afford to have pieces custom-made, and daedric ebony is supposed to be so incredibly rare that few people even know what it is.

Because this isn't Oblivion. Also if the game's too easy, turn up the difficulty.

Yes I agree that there are some things that should be common sense. Though the devs aren't lazy and they've solved the bandits issue with this locked zone levels.

As for merchants, I have mixed feelings about this.
Merchants can sell high level stuff because they are, well, merchants! Whoever in the world can make ebony stuff can sell them to the rest of the world.
Though maybe a compromise. Daedric should be the super rare one, and make it so that you can only make it by learning it from a master blacksmith who lives as a hermit. Or maybe learn it from a daedra, in exchange for an evil service.
But you can't make glass that rare, because people going through the light armor route only have elven and glass gear. Making glass too rare would gimp them.
Or you can make it so that only certain cities will have glass ore and ebony ore for smithing.
