Some comments on the team. Cordelia is obviously the ace of my team. If she has dragon fang and desperation up she can kill Hector with the necessary buffs. She has draw back because if she is trying to escape, then she needs to be in the back. Fury is the best choice of A skill because extra speed and bulk and only 3 less attack than death blow. The 6 damage from fury doesnt matter at all since she's not meant to be hit after entering desperation range and in fact it helps her reach it if she counters a particularly weak sword.
Hinoka, the buffer of the team, yet she is already strong enough by herself to wipe out many folks. However I do have her in a more defensive role as can be seen with escutcheon. Her job is to buff the others, rescue them from enemy range with reposition or hurl them towards enemies, clean up advantageous foes, soften up disadvantageous foes(which I theoretically believe she will survive a battle against with escutcheon), or simply tank a hit. Versatility is her job.
Minerva has a similar role to Hinoka, minus the buffing, but with more tankiness. With Aegis up, she can survive a blast from nino or julia. Ward Fliers is nice, but I think I'd prefer a third Goad Fliers.
Spring Camilla with gronnraven and triangle adept, the worst nightmare of the worst nightmare of fliers, archers. Sure she can use gronnblade, but her synergy with the team is so much greater with raven. Do I need her to do 84 damage in one hit when cordelia can do more in 4 hits? No not really. What every flier team needs is a hard counter against archers and spring camilla is amazing at that.
This team can wipe out all blues and reds with little consequence so the biggest threats to my team as Ive seen so far is nino and julia who can very realistically kill 3/4 of the team in a round. And Hectors, no not a single hector but many of them. The only way for me to kill them without suffering considerable damage is cordelia with dragon fang, but it being a 4 charge move, it can only be activated if cordelia had a prior battle meaning she would be useless against a team of 4 hectors! So against 4 hectors minerva and camilla would have to do all the work while suffering counterattack damage from each fight. I can't say if that would be a winnable fight if all the hectors had vantage.
