Here's the issue.
The boss being dropped to 184 mill is great, grand, and amazing, and I'm 100% thankful for not having to cry over 600+ mill hp in a solo event dungeon, but having an enrage timer of 3 mins bars a chunk of people from getting a fraction of enjoyment from this event, and it did the same for turtle.
I can understand high hp and lower enrage for a party instance, but solo?
3 mins sustaining over 1 mill dps?
Keep the KR enrage timer of 6 mins and you easily drop the needed dps to a bit above 500k, which opens the accessibility just enough to please most of the playerbase and still let the whales enjoy their big dips ¯\_(ツ)_/¯
