Something I just noticed is how the Eden Savage weapons are well tailored to stats. Every dps is Crit/DH, with BLM getting a nice chunk of SpS. Tanks don't get DH since it's technically not a tank stat, but Crit/Det on each weapon is a solid stat spread. They know what stats each class uses.

And then healers. All have Det and a big chunk of Piety, their worst stat once Shiva is down and on farm. Not even a hint of Crit.

Small things like that are a strong hint they know how dps work and have a vague idea for tanks, but have literally 0 clue how healers function in their own game. I think the first priority for them before 6.0 is to hire or assign a class designer who actually plays and is very familiar with healers and work closely with them. We can't go into 6.0 without a proper healer focused class designer.
