Eh? I was pretty sure they were fully implemented on Kro ( Main servers, not just sakray ) and Iro just added them ( 13.2 ) to their sakray test server and are going through the bug testing phase, not for mechanics, but for broken skills, broken stat enchant stuff ( yes, you can now add +1/+2/+3 of a stat to a piece of armor ), quest bugs for the new 13.2 quests.
I was planning on joining in over thanksgiving break, but I decided to buckle down and do school work instead. I'm loving the new Exp system though, MVPing = super high exp and even though you have to stay +/- 15 levels of your target 1/5 of the exp is required to level from pre-renewal.
Edit* also we won't get these classes for a LONG while, If anything I'm hoping we can get up the end of pre-renewal updates. Which is Episode 13.1 IIRC
