dancer/singer spotlight? USELESS RANT NO NEED TO READ!

so as many know already, ivs on dancer/singers arent really important as they are meant to dance and flee from danger. but Llucina new assist skill got me thinking.... if a dancer can dance on someone (and not swap like lucina) then gains another action turn (one time only per turn), she can become a potential threat as now they have 2 units ready to charge at ya. sounds too good to be true huh? well probably, but if the meta keeps requiring better and better skills to counter the current meta, who knows. a dance assist skill that works on other dancers/singers (once per turn only) while also providing self action again like future vision means that PA azura and flying olivia can both dance eachother, gain +3 to all stats, then both can charge at the enemy.
my little rant is just to say i think IVs on dancers matter. even if its not on the same lvl as other heroes.
example is my atk+spd- ninian who has to run swordbreaker and full def investments to tank and kill falchion and all sword users. while my spd+ hp- ninian can fully invest in spd boosts to help her from getting doubled by most units not just red swords. (she runs lightning spd+ fury3, chill spd3, and even spd wave cos why not, she helps my SYtiki and Lrobin double easier)
mark my words! one day there will be a hector armor singer!(manly voice) with superboons where he needs and superboons where it cripples him. watch all the whales resummon just to get the right IVs
