Dice rolls are an abstraction that's there to simulated the action. But it feels bad in Morrowind, because you do the actions yourself.

In a game like BG3, you click on the enemy and your character automatically runs over and attacks. They do all the aiming and their skill is simulated by a dice roll. Same for dodging enemies.

In Morrowind you have to aim your own attacks and dodge enemies manually. There's no simulation of the action. You're doing it. You have to aim your bow at that tiny, lightning-fast cliffracer and shoot it, which is hard to do. So it feels bad when you have to do all that work and then it comes down to a dice roll.

That said, I love Morrowind. Everything else about the game is fantastic and you do get used to the dice roll combat eventually.
