My alliance only has 4 members (active) but we are wanting to set up a challenge as well. Most are lower ranking (only a year into the game) but we love friendly competition! The alliance name is: Facta non verba I am the leader, and you can message me at: nikolini67
I agree with the notion that there should be an aircraft carrier of sorts added to the game. I dont think the break down of light and heavy ships needs to be implemented as the game is not designed like that as of yet.
