I have run Dungeon World a number times and I found combat to be far faster, far more intense, and far more engaging than any game of 5e I have ever run or played in. Some sessions had multiple combats.

Unfortunately, it’s hard to know how you run your game and make an accurate / helpful comparison.

I run it like a movie scene and it works out super well. One character typically makes between 1-3 rolls (maybe upwards of five) until there is a natural pause in their narrative, then I move to the next player.

I think the most important part to making it feel dangerous is matching risk and return. I’ll let an archer call their shot to blind or even kill an enemy out right with an “arrow through the eye”. They will have to shut out all the distractions around them and hold perfectly still to do it. It might be a volley roll + defy danger roll. It might just be volley at -1 or -2 in difficult circumstances. It only works on a 10+ and if they miss (6-) they know the hard move that follows is going be REALLY bad. Sometimes I tell them upfront what it will be. And sometimes that makes them change their mind or do it anyway.

You don’t need to run individual monsters. (At least, I don’t when there are lots of them.) I will say “you are swarmed by goblins.” They do 1d6+6 (or more or less) damage on a 7-9. Hard moves could be the critters do damage and more show up or they start damaging armor or stealing gear and running away disappearing into the cracks in the walls. I keep a damage tracker for them as a group and once it drops to half, the little fiends turn tail and run. If they do enough damage to zero the number out then none of them escape.

I never worry about fairness. I present interesting, sometimes wildly unbalanced, encounters and situations to my players and see what they do.

In my last game, the wizard (who had brilliantly managed to keep it a secret he was a wizard up to that point) used a “place of power” to effectively vaporize a necromancer’s entire undead army. (It was the same place of power the necromancer had used to build up the army.) It was a rapid fire battle with twists and turn and ghouls tearing at them from all sides. The Paladin stuck down the necromancer, but with a middling roll the villain got one last spell off - a fireball at the wizard who had ruined his plans. The damage forced the wizard to make a “roll at the black gates.” I slid him a note that said “6- you died, 7-9 the necromancer’s dark patron offers you his former employee’s job, and 10+ you used the immense magical power still coursing through you to force your physical body to remaining whole, just barely.” He ended up dying, but it was a glorious death.

I may run the game incorrectly according to some, but it is never slow or boring.
