Eh, they're at one and two-thirds of normal (5/3), I think that's enough of an edge to justify Hazou's response (especially since Drain is also a good combat trick, even without Mist Drain). Mostly the change is important because it means that generations of ninja haven't been failing to take advantage of their combat ability, because it's genuinely best for the
group for them to give Chakra to other people instead of using it themselves. Noburi's just, y'know, young and a bit full of himself

. Glib answers aside, for ninja operating on a larger scale than a cell of missing-nin, that kind of efficiency matters more, and your group isn't as hampered by having to protect one or two low-on-Chakra Wakahisa.
