What we're essentially seeing is Blizzard's own clever version of microtransactions. Sure, we can't buy powerful items like those in free-to-play games (which will soon become endangered in China...), but we can pay real money to cater to our vanity or convenience. I've paid several times for server transfers, name changes, and even character re-customization. My wife grumbles whenever I shell out real money for those things, but I'm sure she'd pay to morph her former main, a Troll Priest, into a Blood Elf in a heartbeat. Even Matthew Rossi would pay good money to turn his Human Warrior into a huge-like-Rossi Draenei. There's only one problem, though -- they can't. Race change is one thing Blizzard hasn't given the go signal to... yet.
Anything's possible, though. Years ago, Blizzard unequivocally said that they would never allow PvE to PvP realm transfers. See how that turned out. What other paid services do you think Blizzard lacks? You probably already know that I'm all for race change as part of character re-customization. But how about paying for levels? I mean, despite all the changes they've made to make leveling easier, I abhor it. I'd gladly shell out some cash to get a high-level character right off the bat. What other paid World of Warcraft services do you think the game needs or players want?
