when it gets real busy S ranks will blink in and out for me on PS4, i've easily done Odin with no blinking problems several times.

either there are alot mroe people fighting the S rank, or the hunts are not quite like Odin/behe just yet.

doing it your way would make it murder on healers, also. i've had to let many people die on Odin and some S ranks for that reason. i couldn't even target them XD. (it even happened when my friend was tanking odin once...though he came back before he got destoryed)

still though, i'd prefer seeing the mark first. since hopefully less people will get AoE'd if they can see the warning markers lol.
