Raider IO is toxic

This is true. I agree there.

However, this is somewhat true depending on the group composition you both play with and fight against, as random is random.

Earlier, I made a thread on allowing for a group size slider. Seen here: I think there should be a group size slider for all content

Torghast is the one to set the precedent going forward, not Heroic Dungeons from now almost ten years ago.
