It technically would, but the 10% drop rate gain per person on an already low drop chance would pretty much be ridiculously negligible.

As for the OP, yeah we really need a big increase on the material drop chance and more access to these materials overall; I've never really considered grinding out materials unless I was extremely desperate for them, since breaking them down from equipment is infinitely more reliable than killing mobs for hours with minimal returns. With crafting material drops being spread out across the dungeons there'd also be a reason to return to them besides the leveling process which I think is just better for the game itself.
