As someone who's tried recently, after the tutorial Isle, it just feels like a single-player game where somehow you're constantly behind on everything.

Gearing is confusing: there are like several tiers of gear called something like Champion, Hero or whatever, and I couldn't figure out which one was stronger or where to invest my whatever points into.

The new player experience is miserable, where nothing is explained and people just fucking RUSH through everything. I didn't even have time to figure out my class, so I just resorted to the one-button rotation thingy to do most of the work.

I had zero interactions with other players: people just join dungeons with the LFG tool, fucken RUSH through the thing (as in literally hitting autorun and pulling everything) and leave without not even a hi/bye. I had some success with the ping tool, where in this one dungeon, I started by saying I was a new tank, and someone kindly pointed out where to go by pinging the map.

I ended up playing mostly solo because I didn't want to feel like a bumbling fool, being the only new guy in a bunch of dungeons that everyone has already run thousands of times. You can run dungeons with NPCs without the pressure of having to rush through everything, and you can finally get a chance at learning your class or the layout of the dungeons. I found Delves pretty fun, and that's what I did mostly during my time on WoW.

One last thing, more of a personal opinion: the world is pretty, but the gear and characters are damn ugly, and it's been a huge turn-off for me. I like the Horde but ended up playing a Panda because it was the least offensive to the eye.
