I don't understand the argument that reactions interrupt the flow in a turn based combat system. If it was RTwP, then I get it but turn based is methodical by nature.
The biggest argument I can think of is for multiplayer. Reaction pop-ups will result in many more times where most of the players are forced to wait for a single player to make a selection. Thus, everyone would have to pay attention to the entire combat and not just their own turn.
But honestly, this isn't a very compelling argument. Is it really the worst thing if, once in a while, you have to wait like a minute or two for your friend to come back from getting a snack?
Finally, here are many ways of addressing this: -Allow the option of toggle or pop-up reactions -Add a timer to the reaction pop-up window
Yeah, it's not compelling at all. If your friend ran off to get a snack, the game gets delayed regardless if it becomes their turn when they are off to the fridge. I mean that's the nature of multiplayer. You will be delayed at some point if everyone isn't paying attention to the game.
I don't like toggles because there's too many times I forget to turn it on or off. But I'm guessing that's how Larian will handle reactions. It'll be cumbersome, just like everything else in the game.
I can see timers but if it's too short, then players may feel too rushed in their decisions (not that reaction choices are that complex).
