Since I haven't been around all that much within the last 2 years, I was like "yeah! finally 5th job!" Then I finally took a look at the KMS patch notes for 5th job. One skill? What? I was expecting a full set of skills. That's disappointing... You'd think that they would make an actual 5th job instead of adding skills over time.
Adding skills over time is a way we can measure progression and help minimize the power creep. It may not be the most exciting way to do it, but hey. YOU CAN STACK POWER ELIXIRS TO 3000
