i care about the end result, so i will say if those changes made it on average the same amount of time and effort premade pugs vs RDF queu for the same end value in gear and badges and character progression, id LOVE THAT.
Even when you spam LFG and hold onto queust theres a LARGE amount of time during which putting in that effort for the payoff is still more efficient than leveling questing during that time. I think its like 6 hours of effort is worth it if you complete the dungeons and the quests, because you get farther. There are write ups about it on leveling guides.
I have a thread to discuss this and what would work/what wouldnt, and how far pushing back RDF in this world would be too far.
