a lot of players having a problem to find a team for spvp. and i think its one of the reason why spvp community for guildwars 2 is not that big and not that exciting. i think we need more features so people would enjoy it.
i know arenanet will be adding the ranking feature soon so im suggesting.. maybe instead of having 1 organization called guild.. maybe you could add team as another organization that one can join.
