I'm curious about everyone's teams, particularly, do you have a team on both alliance and horde, above level 45?

I'm debating whether to level a new team on alliance, where I have previous 70 characters (non boxed), or on horde where I have boxed 70 characters (only one team).
I really like my alliance characters, but I'm unlikely to play them if I don't box. Whereas, if I level characters on horde side then I can expand my teams abilities. Decisions.. decisions..
