Both are important, even if everyone is getting lots of action (feels fast), if combats end up needing to be split between multiple sessions, people are going to complain that the story isn’t moving or that they have been stuck in combat forever. If people are waiting 30+ minutes for their turn, they are going to stop paying attention and do something else while waiting.









TBH, 5e hates secret roles. (yes, i know this is not a 5e specific post, just a personal gripe)
There are way too many abilities that trigger on a failed roll or can be used after a roll that this kind of play style straight up conflicts with.
One of the worst ones for this kind of thing is the soulknife rogue’s Psi-bolstered knack (that they get at level 3), with both triggers explicitly on a failed roll and refunds if the extra dice if it doesnt make it succeed so you cant even include mystery if the reroll made it a success.
