At this point we do so much damage even on level 90+ uniques that having any tank is kinda pointless because they can never draw enough aggro. I've been find it better to go with 2-3 attackers and 4-5 healers and just dunk on every fight.
Helps that with a Rank 20 Flash Fencer the Capable Hands Master Skill lets your Talent Art be 100% charged at the start of battle so you can use Lucky Seven right at the beginning of a fight (and if you want to take it step further beyond that also use Signifiers also with Capable Hands and as well as Glittering Melody (from a Rank 20 Troubadour) and Noah with Resonant Flag as one of his Master Arts to spread the invincibility buff to the entire party and then playing as a Signifier the rest of the fight to just constantly keep the buff up the entire fight)

Just some fun time quickly dunking on level 100s
