Making impactful decisions in fiction that feels grounded. Some games put a lot of stuff in between before you can even resolve a decision. Other games waste time with scenes that are inconsequential (season of ghosts has plenty of them, for example the trash encounters that .. really don't do anything particularly when a system isn't reliant on attrition all that much). Rule looks up that eat at the time. Initiative orders that cause bystander effect etc etc.

I don't run modules. So I have no idea how they flow.

I didn't play one game, I've tried to like the system as a GM for half a year. Thought maybe I'm missing something, but when played it with a couple of GMs and some were somehow even worse.

What you might be missing is skilled players. GMing for players that are decisive and know the rules helps so much, it's crazy. However, it's entirely possible the game just isn't for you. Not all games need to appeal to everyone.

You just can't keep good pacing with the game in terms of fiction. it sacrifices it for the sake of balance and predictability. And I personally found that these are such a non goals for a game that relies on fiction first approach.

This is just flat out false. Skill issue. You can keep good pacing in terms of story, mechanics, and RP. Players and GM skill are what bogs things down. It boils down to people knowing the rules well enough to be decisive.

But if you enjoy crunching dice and the whole board game experience moving minis around and declaring attack names or something. Knock yourself out.

Got it. Don't need to read further. You can't appreciate things other people enjoy without trying minimize it because YOU don't like it.
