If everyone unsubbed, why would BW do anything? Everyone would be gone, heck, if anything, they'd see it as a waste of money and just rid themselves of the Oceanic servers altogether as no one is playing on them because they all left. xD
Pretty much everyone I know that has unsubbed (myself included) has stated that we would renew once our server Population issue is fixed. And guess how it is fixed? Merging all three servers together.
