Unohana was hyped as being one of the 3 Senior Captains and not to  mention the best healer within the Soul Society, losing her was a massive blow to the Gotei 13's fighting force.

You forget that Unohana can  put people back  together after they were cut in half, that's invaluable healing abilities.No matter how few healers died, without their Captain, the healing capacity is drastically  reduced, to to mention not having any Captain makes their squad  vulnerable to a future attack  and given that squad has  ZERO  fighters aside from Unohana, they're screwed in the next Stern Ritter attack

So what benefit was it to take out the best healer and one of the best  fighters within the History of the Soul Society ?Why couldn't Shunsui just had a regular training/sparring match to  have Kenpachi  unlock his powers  ? Why did we need to lose either fighter ?

You forget that Kenpachi even with his power up stands no chance against Bach, due to plot armor,  only Ichigo can beat him with his stupid, poorly retconed bullshit Quincy powers. Also that doesn't make the idea of  recklessly killing the best healer in the Soul Society  any smarter. Think how much fewer people would  die within this story if Unohana was still alive.
