Aside from her chases, she is an excellent chakra hoarder for your team and will greatly help with future ninja that have expensive chakra costs (i.e. Kazekage Gaara with 80 chakra mystery). This'll enable your really high cost jutsus to be used by round 2 or enable your entire team to pop off all your mysteries at once.

But there are better ninjas to help you with chakra ...
Of course there are better ninjas that can help with chakra, but not all of them are out yet (Kage Summit Temari), only give a small amount of 20 chakra (Sages), or are inconsistent with the chakra gain due to depending on the enemy to give it to you (Ao). And as always, enemy tactics can mess with your combo, but a good team will still have a debuff removal, but that's beside the point.

My main point was that for a consistent chakra gatherer, she's the most dependable one at this moment.
