Today, I was made aware of an effort to datamine some upcoming changes in Game Update 1.7 . This information was passed along to me from an anonymous source, but the original miner would appear to be a user by the name of Kamii.
So far, the information largely relates to changes in classes, including new abilities, and revamping some of the already present abilities. For all this information, as well as my opinion on the matter, hit the jump.
EDIT: After receiving a few tips from some anonymous sources, I'm updating this post with more accurate and more concise information about the previously posted leaks. Hit the jump for the updated article, as well as to discuss the information contained therein.
