Very true. The issue we had was that with an entire community moving all at once, they did not try and fit in with the current server vibe, they just moved in and continued their same way of interacting as all their buddies were there as well. Nothing changed for them except the web address, basically.
I would somewhat compare it to someone moving countries to one with a different culture, and then staying in their own little community and continuing their same ways as back home, with no effort to interact with the existing residents and find out about the local culture and ways of life of the area they inhabit.
