Thanks, all.
Dendrobium - A glass cannon and first turn alpha specialist, her bonuses are geared towards pumping out a burst of two special attacks before the enemy gets a word in. She can work well in a vacuum of other powerful units, but her power isn't up to long duration fights. Despite her rather self centered abilities, she does grant the party a 22% attack bonus.
Out of isolation, a Dianthus or Maple would be better choices, hitting almost as hard or harder on turn one and boosting allies in endurance fights.
What's the deal with that, anyway? Still, it's no loss having one of the others. We just have to double down on filling out those 'request for blooming' surveys in game. It's hard to argue against Saffron, though. That defensive spread is top tier, assuming it's the same as the wiki.
