Access to raids and gearing for success in those raids is easier now than ever before. Just getting access to a raid used to be a time consuming endeavor. Do you remember attunement? Or leveling lock picking on your rogue for a week so you could circumvent a key that was unavailable? Or finding a 5 person group who was able and willing to complete a dungeon and then traveling through hostile territory to get to the entrance? All of that is gone. It's gone because they hope to entice more casual players, despite the fact that those things were challenging, and fun, and added a lot of uniqueness to each person's abilities and experiences.
