Realistically, if you can clear an Extreme trial, you can clear a Floor 1 and 2 of an average Savage tier. It usually gets more rough after that, especially in PF, but the first 2 are usually trivial enough to get done casually.
In any case, there are a lot of reasons to believe it'll be casual enough:
- It's technically possible to do it with 12 (although they may not have enough damage). That means only half the players should have to do mechanics correctly.
- The announced incentives appear randomly on different data centers and all seem to be designed as if this will be a heavily PF'd fight.
- If it's not PF'able, the BA/DRS discords will probably pick it up and just do callouts - which if you've done those raids, they call them out so well and smoothly that all you have to do is exactly what they say, and it's a clear.
All content is worth a try, but realistically a lot of people won't due to anxiety or other reasons, so that's just how it is.
