Tabula Rasa crew has sent down another missive from the heavens today, instructing everybody to give themselves a big pat on the back for the rigorous testing that made patch 1.6 a success. Looking forward to patch 1.7, they've stressed that while the changes to the Ranger sub-classes are their first and primary focus, they will be making an effort to look into every class to see what needs to be changed. Specifically, they mention making a global pass on all abilities for every class sometime between now and patch 1.8 and 1.9.
In the immediate short term, they're looking to make changes to the minion system, which should give classes like the Exobiologist a little more utility than they have in the current build. Pets will also now receive a damage bonus from the mind attribute, giving them some added reason to spec something other than body for a change. In addition to some other, smaller UI changes, they also sought to make it apparent that the current costs for redeeming items with CP tokens is not set in stone, and can and will be tweaked if they're not seeing the desired results server-side.
