The problem is that you hear this alot because well, it's true. Their logic makes no sense when they change things like this. What's more, is as someone else said, one of the Devs was TELLING us to form raid groups for it. And as someone else added, it's unlikely many will bother with this anymore as the only reason it was done was speed and ease.
Throughout the years I've more often than not been a strong supporter of their developers and so far, I still am but sometimes I sit back and look at changes like this and scratch my head, asking: "Why?" Because I know in their position, there's just no way I'd come to the same conclusion. It pointlessly hinders players for no gain. Maybe I didn't intend for it to be trivialized but it's been like this for months, at this point, I'd say: "It is what it is, leave it alone, people are happy doing it this way."
Edit: I'm not sure what things other MMOs do right that he's refering to but the 'ass backwards logic' was absolutely true.
