believing you got a dedicated team of player that would like to shoulder the responsibility to create one in the horde then yes. If its still you and your real life friend, i suggest its the best to keep things as they are.

While TTF style guild would sound like a great idea but the dedication require to pull something of that scale is not an act mere casual with day job can pull, do also note that TTF got a sponsor on their back for the things they did so they can focus doing it and it only.
