Warcraftlogs has an active admin who loves WoW, is constantly improving the site, and looks like they care to improve raid tools and add new and interesting features (such as execution ratings and whatnot), they won't be a paywall to get rankings (currently you only rank on WOL past 150 is to be a paid subscriber).
Even if you get the worldoflogs.com people to fix their shit today, they have consistently demonstrated a lack of enthusiasm for this game and it would really be a stop-gap measure to retain their paid subscriptions. At this point, I don't know why you'd -want- to save WOL instead of supporting a new community that is responsive and passionate.
