Yeah, but as I see it, those benefits are mild comfort or convenience issues. The 'Dollar Bill' issue is a potentially fatal one. Even with Huntress and her cape there, you can tell that it's just held on by the crecent moons. If Helena put thought into the design, there's probably some way to detach the cape in split seconds. I don't see how Dinah could rig a quick escape on the trenchcoat. If she just wore a short coat and some pants, she'd get best of both worlds.
