For those who are wondering about servers, this will only be an issue in the short term, as once they have sorted out the various stability issues, there are plans in place to merge all the servers into one. So, the server that you choose, really isn't all that important in the long run.
I don't agree with comments about the game being P2W, as there is nothing currently avaliable via the 'zen' shop, that gives you an unfair advantage over regular free players. In fact, the only thing that you really 'need' to purchase from the zen store at this time, is an extra bag, its not necessary, but it helps, the same with bank slots, handy, but not the highest priority at this point.
