I believe Noodle have the most devoted players. They probably have a deeper understand of the game then anyone else of W61, and play most actively and efficiently. However, I know them, all this effort also means they burn out the fastest. Limited Hauls is not as taxing on your sleep/real life, so they might stay for longer. We'll see.
You are wrong about Riot! changing their recruitment strategy, the only change was we have gone from is not having a name of someone to spam on our profile, to having that name up there. We have always been open to new people, also those without the devotion and understanding (which is what caused the wave of bad comments about us), and many of them used the chance they were given well. Some unfortunately, have abused it - it's impossible to predict with 100% certainly if the new recruit is a "user" or an "abuser".
I really believe it's a greater, even if more painful, challenge to make a great tribe of decent-to-very-good players then to be very selective and make a great tribe only inviting those you know were great before.
