12% once vs 12% stacking from mystery and chases. GNW has 2 chases and your team would do at least 35 hits, if her second chase triggers. Her mystery also hits entire team.
If she triggers all those requirements that's 36% boost in 1 round.
As the person mentioned above, he let her lived and she returned and wrecked his team in 1 shot.
She comes to say hello and goodbye to Midnight Blade row.
I really wouldn't underestimate that passive of GNW Temari that buffs her damage after each combo. Nor her multi combo chase which does a LOT of damage. Not to mention the fact that her mistery removes the buffs and shields from the enemy, which is good against teams that rely on that. She is MUCH more offensive. And by removing the buffs of the enemy (thus removing their damage potential) you could also say that she is good defensively as well, since without buffs the enemy will do less damage.
Of course, KFC Temari is good too since she does give shields and buffs to wind ninja in your team.
The one downside with the GNW version is that her mistery has battlefield cooldown of 1 so can't cast it in round one, but to be honest, if that was the case, she would have probably been a bit too strong. I prefer GNW Temari more. But that is just my personal preference. Now, the reason people don't use GNW Temari that much in China is that there is a similar but apparently better version of her, namely Swimsuit Temari. Or so I've heard.
