I think this is overrating Akane tbh
Akane Taijutsu + Flame Aura is good, BUT: That's assuming she gets to go first, assuming she can close in on the enemy for melee attacks, and assuming they don't have any other kind of tricks that can deal with it, or a better buff than her. And her alertness and athletics aren't any more impressive than your typical chuunin. Hell, they're not even much more impressive than Hazou's. So if her Spec-Jonin specialty is to be Taijutsu, she needs to be sure she gets to use her taijutsu and win as a jonin-tier combatant, and I'm not sure she can do that yet, not reliably at least.
