Probably depends on the content.
I like the new raid. I don’t really care for the new dungeon.
The zone is mid. I don’t like the new weekly punishing you if you don’t sit around waiting for it for several minutes before it starts.
I liked tank Brann, but fun was detected and promptly deleted.
We can only visit downtown by now so it is a strong possibility they will expand the place.
You show up in Undermine and the goblins are like “ find an apartment! Get a job!” And we do. It’s not that fun lol
There is just way too much RP and gimmick quests, and unfunny jokes for my taste.
Apparently some people like that kind of stuff…
The flavor of the zone is awesome. You dance and the locals start a dance party with you. You die and the locals loot your body. Are you a gnome? Prepare to be relentlessly mocked. Goblins are so cool because they are like actual real life people in their behavior but the city is so busyyyyyyyy there is so much going on with cars zooming all over. It’s wow’s nyc. And busy environments like that give me anxiety. The zone is fun but I can only take it in medium doses
I didn’t vibe much with the new content either…the theme wasn’t really my thing, the dungeon pool wasn’t my thing…so I’m with you on that.
Ofc, no hate to those that are enjoying! gl hf this season! 
All of these bonus maps they introduce in every expansion are usually a cesspool for grinding and farming to nothing substantial or impactful on the theme park design philosophy. I don’t know what else you expect lol
I’ve found myself engaging less and less in wow’s content these days.
Undermine is pretty boring IMO.
Retail has fallen.
Undermine is a breath of fresh air.
Or at least some kind of air.
Either way, I love the zone. There was clearly a lot of love put into it. It’s so dense with charming details.
I’m sure people feel the same way about it that I felt about the emerald dream. It wasn’t for me, and that’s fine. It’s nice to see something different, especially as we’re staring down the barrel or a prolonged elf-centric multi-expansion narrative.
I made it about 10 quests in. Never got my DRIVE because, meh. Waiting for housing. Playing SOD in the meantime. Was in HC, but not playing with DDOS attacks.
I haven’t played much since the patch to be honest. I really wanted to love it but I just don’t like goblin content in general. All of the gadgets and stuff seem really out of place in the world and they’re just annoying. This is just my opinion. I look forward to being out of this area.
I’m enjoying it! Although it doesn’t fit in-character for me, I do enjoy drifting and doing SICK donuts while tooting my horn. 
The place actually gives me FF7 Midgar vibes. As for the raid, its a ton of fun, my favorite fights are probably Cauldron of Carnage and the One-Armed Bandit.
I’ve shared it with some of my non-WoW friends and they’re shocked since its not what they thought WoW was like (and they’ve actually expressed interest in playing now lol).
Sure, I can see why people don’t like it for this or that. But I’m just taking it as a comedic interlude before getting back to the usual.
I dont mind it but I would like it a hell of a lot more if the car didn’t exist or controlled better. Some the WQ’s also just suck for no reason.
I am very much happy that we finally see goblins done justice. Blizzard did a splendid job here. Now all we need is a boat route to Kezan for goblin players and the patch is perfect.
I thought Undermine was a fine and fun shakeup, and I rather enjoyed how it played on the content loops we are familiar with using the new mechanics. IMO it actually felt nice having no flight for a bit… I also like the story and its conclusions. With all that being said, I do prefer Hallowfall and Azj-Kahet and will therefore be more excited for the 11.1.5 Renown content. I would say the factor of ‘wandering for X months in the same aesthetic’ is also in the mix.
Like you, I did prefer Azj-Kahet quite a bit!
Are you the minority? Hard to say, forums are 1% of the game populace, and insufficient as a control group as such, 10% maybe, possibly even 20% of the game’s masses would be preferable as a “sample”. But given that .5% (or 1% if forums is as much as 2% of all players) or roughly half the forums have each declared either loving or hating Undermine either way… I’d say not technically the “minority” if I’m allowed to erroneously use the forum as a control group, which I am loathe to do.
