Server merge will make those players who unsubscribed come back for sure!! This is a win for BioWare/ EA! Not only, it will make us Oceanic players happy because of the healthy server population again, for you guys, BioWare will have more moolah because of the subscriptions!.. It's both a WIN-WIN for all of us.
I think Y'vaine/JcPogi really hits the nail on the head with this comment!
I know Bioware has counter argued they want to give the APAC community the choice of which server they play on but I do think a gamer, regardless of their intentions to RP or PvP would rather be on a well populated server than a server with very low population.
