There has been only 1 fight in the entire game where raise was intentionally abused, A4S, this fight had a mechanic where it would put 2 debuffs that could be passed around (Nisi) but couldn't be stacked together on same person, these debuffs ticked hard at first but gradually ticked less as time went on, this mechanic was sent out relatively early on in fight (legs were still needing to be killed), these debuffs were essential for a mechanic once you could hit the main body permanently, this mechanic was Royal Pentacle where it spawned 6 orbs in center which were randomly colored 1 of 2 colours, these colours were the same as Nisi debuffs, you had to pass the right debuffs around and soak 1 orb, this mechanic happened multiple times before enrage.

Want to know what people did because the mechanic was that troublesome, they let Nisi drop off, had 3 people use server ticks to gauge when they can run through 1 orb and still hit a 2nd this ofc killed those 3 players, where they were raised up and continue the fight, healer lb3 was used for 1 set of these, all of this was a Dps gain over handling the mechanic properly.

No other fight in this game has it been better for a death to occur and res them up, so long as this holds true the majority of people will avoid dying where possible, the time to reevaluate res will be once the devs start doing mechanics as bad as Nisi+Royal Pentacle again.
