This is still pretty early in the world but 73 players is not a major issue when HOGS (incompetent or not) have hit 80 already.
Worlds it seems are so different to how they used to be. At one time, tribes rarely hit skill level 40 if they did it was late world. Now its a regular occurrence.
We just recently upped ours. But some tribes have been over 40 for a while now. In fact, one tribe, I think it was yours Titus, actually started with UNITY that shocked me to be fair - it didn't make me grumpy though, insanely jealous is probably a better way to describe it.
I didn't jump on the forum to discuss it though, i just accepted it.
It looks like there is a lot of dodgy stuff going on in this world and having 73 members seems like a minor issue in comparison, definitely not worth getting upset about.
