I went back and played a little while ago. Dungeon Finder was near instant, and would stick me in a dungeon I had zero context for. Magically transported there. Nobody was from my server. No conversation/chat. The encounters/dungeons themselves were utterly without context (I never had a clue where they were) and felt like clicking through to get loot with no sense of storyline.

For me, that's a huge negative. I remember that the dungeons on the shattered plains (i think) specifically revolved around the shattered hand orcs or whatever. They synced with the area and the quests I'd been doing locally. It felt like a cohesive world I was involved in.

I cannot argue that the new system isn't efficient. It got me playing and it got me loot. But I never learned anything about anyone. I never engaged with the story. I'm just old I guess xD
