The base game isn't so bad, come on now!
Here are some of the things I heard about Morrowind for years and years: "That first mudcrab we meet in Seyda Neen always destroys us. Because this game is so much harder than Oblivion!" ... and also... "Everything is dice-rolls, Renee, it's not really you who is hitting the enemies, it's your characters, and you'll die over and over and over as you miss and miss and miss!!"
So I believed this. When I began playing MW in 2018, I expected the first crab would mop the floor with my character, and it would only get worse from there!

But it's not really that bad at all.
1). Choose Major skills which coincide with the weapons my character will use, and
2). Go into battle with plenty of Fatigue, (really important)
3). Go
headstrong into battle. Do
not back down, especially with melee-based characters. Get those hits in early, before the enemy does. Make sure to dodge. When the enemy takes a bite or makes a swing, try to stay out of its range.
Following those three rules, I was surprised to find the startgame can actually be easier than I thought. Fatigue makes a huge difference when it comes to combat. Those others who warned me had characters which missed all the time probably because they were low on Fatigue, probably due to too much running around. Since my characters tend to walk a lot, they've always got plenty of Fatigue.
And this goes both ways. Enemies who attack and miss attack and miss over and over... it's a slippery slope down for them, too. Because they're using up their Fatigue.
Regarding magic: Yes, magic doesn't regenerate in the base Morrowind game, but this is also true for magic-using NPCs as well. They cast and they cast, while we dodge and avoid. Pretty soon they can't cast anymore. They break out whatever weapon they've got (usually something spindly). They make a rush at my character. From that point, I've usually got them.
And the thing nobody ever mentions: Magicka doesn't regenerate in real-time, but the magic in
items does. Therefore, if we're wearing a ring which heals us, that ring is going to regenerate the magic our characters cannot.
Not that I'm trying to convince anybody here.

It's just that so many times I've heard how impossibly hard MW is, and yes, it is challenging, it is difficult. But my experience is, it's also not as impossible as so many gamers told me in the past.
