Quote from user_938036 »Didn't they do something like this for Ravnica with the guilds? They had them ranked based on players wins. I don't think it had anything story related to it but it was interesting seeing each guild ranked, I think one guild(izzet?) led the majority of the time.
That was awsome, and if they did the same for the factions with the city at stakes it would have been cool too, but might have made people feel forced to go play when they don't want to or their voice won't be heard. Or that their voice won't be heard due to being too weak.
UR and UW were the top two when they polled last time. If I remember correctly all the Ux guilds were highly rated. I believe it was based on what people liked rather than wins. But information like that is somewhat biased, it's known that more enfranchised players tend to lean toward blue and newer ones to Red and Green so that can always skew results of surveys.
