Well, revamping might not be needed with the lower max ilvl. A lot of issues are generaly due to skipping mechanics. And once they cant be skipped, its most likely going to be fine. Some extra difficult fight in the middle doesnt harm, void ark also has these. And its those fights that for ilvl cheese would be a way to discourage it.

But in the end, as the other raids are optional, i dont think this will be enough. But at least it will be a major improvement.
