In today's update we're adding tradeoffs to some elite specialization lines with changes to chronomancer shatters, an overhaul of scrapper specialization traits, and some improvements to the base necromancer Death Shroud, all in order to make the choice of an elite specialization more meaningful. We're also doing some follow-up work on the changes to berserker from the last balance update to tune up a few areas. The other main focus of this update is adjustments to core trait lines on several professions to address some pain points and power imbalances. Finally, in this update thieves are getting an entirely new skill type that replaces traps. For full details on these changes, please see the individual profession sections.
