Ever since the open beta, the rewards they've been giving out have been so stingy that raising characters just isn't fun. They keep saying there's no need to spend money, but at that point I'd rather just pay and play on the official server. The only real advantage is that it's based on 2.0.
They keep saying, "No wallet, no problem," but that's a scam. In reality, progression is so slow and the rewards are so stingy that you're pushed toward spending anyway.
