They say more or less the same as we do.
The content is fun but not ideal for 24 people in PF and they are pretty miffed because it is not the difficulty that was originally planned.
If anything their thread seems even more consistently negative the ours.
For your question for whom this:
Bis gear they said in the past that they would be looking into alternate ways to get it.
I don’t know if this is the correct way but I give them kudos for trying it.
For the why PF the content.
I genuinely think they really wanted to do a raid that is harder then normal in 24 man and brings people together.
It was probably really planned to be a step up for those who want to try harder content with the idea of raiders helping new people out.
They just completely butchered the finetuning of the difficulty too much into one extreme because they didn’t realize what 24 people means.
I honestly think this is the result of them only testing things in a test environment because no way they had 24 of their people doing this thing normally and thought “yes, this is the correct difficulty”.
