Why is something so simple to set up having to be done by your community? It's a very sought after mode, and I myself would very much want this. In fact it's all I'd do, and I try to get my friends to do it, but they dont seem quite as interested as I do in it. I'd love to meet up with more people who would want to do this without having to have some sort of community outreach.
TL;DR---> Devs, patch in a 1 vs 1 mode.
