All the battle mechanics in that boss tell one thing "Pay attention to the boss, don't overrely on aoe marks" and all the mechanics do that without putting the party under a real risk, if the dps die they can get up with a res and practice as well as practice that principle of not relying too much on aoe marks in further trials. Coincounter is far from a boss with crap mechanics, is a good teacher that punishes you if you do bad but never hard enough to make it frustrating, the problem are the players that refuse to learn or adapt and tab into other things as soon as they die once even when the fight is not over, you have a good teacher, be a good student.
