To my understanding, there are no more servers with available housing on the NA data centers. It appears most of the free housing is on the JP data centers. NA not having enough resources to deal with its population is its own problem, to be sure. I don't think it's really reasonable to expect someone to transfer to a server that majority speaks a language they may not know where they may have very high ping to access housing. That was an applicable thought prior to the split, but since Crystal was added and the data center was split, the population has evened out for NA a lot.
