Did the devs suddenly die and declare you the supreme overlord of Alex Savage? Who are you to determine what is "intended"?

We aren't given any guidelines in endgame raids. Just hints and freewill to think for ourselves how to handle different mechanics.

If every fight was a strict "Do X to win" I'm damned sure raids would end up dead as creativity and figuring out how to deal with mechanics in your own way is a big part of raiding.
