I play a Ninja/TA and on a Team-8 mission I had a Pain Dominator asking me if they ought to do more to keep my pets alive, since I had to keep resummoning them so often. I simply told him, "Nah, they're expendible ... and they know it."
I'd often wind up dismissing the one or two surviving Genin or Jounin after a battle, simply because they'd taken so much damage, and just resummon them ... followed by a quick round of rebuffing. Usually wound up costing me less time than trying to hand them all green skittles to eat or waiting for healing powers to recharge. So long as the summoning powers have recharged, I have no problem simply resummoning Expendible Ninjas a lot during teams.
It's the end. But the moment has been prepared for ...
...by accepting that the Genin are really just short-term +res buffs, like really good orange inspirations.
