Sorry - yes. Wasn't trying to argue either. I got my first two packs on Friday and when the cards print well they are so cool so I want everyone's cards to print well!
Sans serif typefaces work better at small sizes. If you want to put white/light text on a black/dark background the rule of thumb is to step it up a size and/or boost it slightly with a thin border, although that border trick won't work well with a serif font when it's too small because it'll just turn the letters into blobs. Increased leading also helps but, of course, then you lose physical space.
