On the endless harvest, the actual endless quest, you encounter Mildred guaranteed 100 after the first 'Lap'. At least the Arb/Mus can de-stealth the whole team and then decide between top-ups or nuking while the ShB's go to work. Much like any Farmstead curio, Mildred is RNGed and who knows when youll see her. Snakes are pretty beefy, so all she can really provide is stuns - not great when on a timer. Considering you need those fights over ASAP, having a fast projectile-healer can be handier than MrsJudgement, even if her healing is vastly superior. They'll both get stressed, but they're practically equipped to deal with snakes anyway. I typically always pair ARB/MUS with ShB - in fact, I usually stack ShB's for snake-fights. Medium or Long missions give you ample opportunities to sort that out before a possible snake-fight.

Nothing better to do? Might as well get tonnes of speed. The bandage effect is nice and all, but being able to guarantee first-rounds as ARB/MUS (be it to heal or shoot the back) can be delicious if setup properly. Ah, the joy of stacking side-arm in a corridor fight (or room battle) so you can have sonic-the-hedgehog flare immediately when you camp - on top of marching plan for everyone else.
