The problem with Tripling Down on Shadowbringers Job Design

[Sjol]

It's because the Development Team is scared of job complexity.

I very much doubt they're scared of complexity. Why would they be? You outlined the actual worry yourself -- a very reasonable fear that their job design will lock jobs out of prog content and the race for firsts.

Balancing jobs against fights is incredibly difficult at the extremes as shown by not just this game but other MMOs as well. The goal of making jobs feel different and jobs be balanced are at opposition. I don't envy the job designers who are having to do this.
