It literally makes no sense since there is no other raids being added in HW to remove creator from the raid finder.

One of the best features of Raid Finder is the ability to select Duty Competed / Duty Incomplete.

By moving it to the Duty finder you removed the ability and people try to sneak with bonuses and generally don't even try to queue via Duty Finder because they know there gonna be bonus people.

Also make 0 sense since fights like Thordan are still in Raid Finder.
