How to make the 3rd raid difficulty work

[Arutan]

That or the clear rates where so low that they wanted to make content the people would actually do?

When the clear rate is low, it means it's good. It's raid, not a walk in the park. Raid were always mean to be harder than anything else in a MMO, dedicated to end-game player to spend their time on it. The story mode exist for casual player to do it and enjoy the bosses and the map design without having to face the hard difficulty of the savage mode. The more time passes, the less we can differenciate both. A9S is a joke, anyone can do it eyes closed. A10S can be done as long as you have at least a half of brain.
Lots of people have stopped playing the game for weeks now 'cause they already cleared all floor times and times again, and we have to wait 6 months before the next expansion, with nothing to entertain us. Dun Scaith? Mean to be casual. 1h a tuesday and done. Zurvan? Well nope, low difficulty too for casual to enjoy it because normal isn't enough for them. Clear within an evening then bye.
