A building of an idea on a pre-existing one:

I would like to see all the guilds broken up the way the thieves' guilds are. Each guild will teach you the basic skills you need to survive, but then each guild has its own specialty. This would make sense for the warriors' guild because it is unrealistic for ever warrior guildmaster to know how to teach on every specific weapon specialization. All, for shapeshifters, it'd be nice to see guilds that specialize in offensive forms, some in defensive forms, and so on. The major cities would have various guildleaders, much akin to the thieves' guild's kingpin. This helps new lines of roleplaying, gives newbies visible leaders to ask questions to, and provides the endless amounts of people making hero each day to a position to vie for within their guilds.

Something to think on anyway.
