there's a problem with this: ghysal, selbina and mysidia are already full as capacity, meaning : after the current population move to the new server, space for others will be few.
i'm not entirely positive on this matter, it'l like say "we are good as now, go in your downtown, low-population immigrate".
I'm exagerating of course, but i think it's good splitting people if you manage to bring linkshell and friend together
