If anyone has misconceptions about Island Sanctuary or Criterion Dungeons, they've done it to themselves. The dev information on those has been very sparse. It's not their fault if people go make wild speculations.

I'm not sure why many of those would be addressed, considering it's the first part of a major patch Live Letter and that's usually focused on the new content coming. They might mention some job changes, but IIRC they usually save that sort of thing for the second part when there are some planned.

A lot of this seems to be something that would more likely be addressed in interviews or official statements, or another special Live Letter like the 10 year Live Letter.
