i am playing in a campaign based on Pathfinder 2nd edition rules. My GM decided to introduce the house rule of rolling initiative every round, basically altering one of the base concept of the game.

The result is that every round is very different from the others and in my opinion the dynamic range of possible outcomes greatly increases.

Now, i was wondering what was the reasoning behind the choice of making a single initiative roll at the start of the fight, was it for the sake of simplicity or there is something else?

Furthermore, what else do you think we sould absolutely change to keep the game balanced?

Thank you
