Response is a year late, but in case anyone else is searching about unlocking advanced classes via gems: From what I have seen you can unlock adv classes 1-6 with gems. Im not sure about the 8th class but I am assuming you can't purchase it with gems because I know the 7th class can't. So yeah. The 6th class requires Evo gauges but You can skip that bs via gems. And for those of you who say it's cheating... It's not, time is money and if you work for your money like me then you know the value of time and money. Spending hours every weekend for a chance to get a class or buy it for a 1/4 hour of work... Yeah. And in response to it devaluing the experience of the game. If you like losing alot and that's what you play games for then go for it. Otherwise skipping a few early on is no big deal. You'll get to earn the other two classes without gems either way. Not to mention considering the game has been out for what, 3 years now? And I first started a few months ago and Finally have my main character made a few days ago (Had to make sure Wanderer was truly the class for me.) So skipping a bit with gems to ketchup to those of you who have been playing this for years... Seems totally fair and in a way increases value of the experience consider how far behind you'd be. I mean, if you start the game after 9 million people, are you really going to want to take a year or so the be strong like them?
