I was exploring WoWprogress the other day and realized that the main list of guilds ranking, the one that used to be a combined tier list, is now separated and cannot be viewed together. That is, you can't see a list with 11/14 ten man groups directly under or over 11/14 twenty five man groups. I don't know when this was implemented but thought it was interesting and worth taking about. It seems to be taking the separate-but-equal stance on the old (and wretched) 10/25 debate, otherwise, why change? At the same time, it's interesting that there's no combined list, yet either raid size can beat the other on their ranking system; if 10s get the kill first, they'll rank higher than the 25s, but will always be "over there."
I like the new system, but just think they didn't commit all the way. If you're going to separate the two, then don't allow 10 man progression to influence 25 man rankings and vice versa (search for you guild, if you don't know what I mean). Alternatively, reintroduce a cumulative list. Just my two copper.
