These are the ones that bug me the most, too. Lunars have a few good options and a lot of mediocre ones, and they often don't get enough Charms to slog through all the speed bumps to the stuff they actually want.
I actually like their Excellency structure: less powerful than Solars in a given field, but more versatile. I wish the writers had applied that principle when it came time to make the rest of their Charms.
