Let me use half a rune page

When playing ARAM, you don't get the extra 10 seconds to finalize your rune page, even in normals it's a pain to figure out a page. If you don't know exactly what you want for your page there is NOT enough time to fill one out. And if you aren't completely finished and saved, if you try and save there's another dialog box saying 'incorrect choices' or whatever it says. If you don't confirm that box you are stuck with the shittiest default page. I don't want future market. I don't want open spellbook. I want to use my rune page that is missing ONE of the secondary runes. I don't care that I'm missing out on the tiniest bit of stats, having the entire rest of the runepage that I PICKED is infinitely more valuable than one single secondary rune. PLEASE at least make a useful runepage the default one...
