Well, clearly, I was in the camp that interpreted "arpfest" as classical arpeggios, not specifically utilizing 0xy (though I figured at the start that either would be following the theme). I've seen the word arpfest used a couple of times on BotB, but a clear definition is something I haven't seen. Referring to the majority of votes, either I wasn't the only one to make this assumption, or these voters were being lenient.
Of course, none of that actually matters, since you're free to vote as you like, and interpret the theme however you like. I just thought I'd explain myself, and perhaps sway your opinion!
