I see. On that note, how would guilds/clans be organized? Is it strictly limited to teams? I'd like to know because I imagine there'd be some sort of mega-group that trains/hires/fights en masse, using scale to its advantage.

They aren't that much different than guilds of most games. Guild halls, guild banks, they make it easier to find people to play with, etc...
