Are you satisfied with War Within so far?

It’s honestly ok.
The lack of a full fledged development cycle, including the super short beta period, is clearly showing its consequences though: bugs galore, unfinished spec, class revamps on the very first minor patch etc.

Story wise, it’s at least far better than DF, even if still rough on some plot points.

Professions and zone cohesion are worse overall, though the zones themselves feel better and Hallowfall should have been an Expansion on it’s own with the rest of the Undersea and whatever lies beyond the Arathi side/or a far larger underground continent when it comes to land masses.

At least the zones aren’t all disconnected like SL and that terrible inter zone padding.

PvP has finally good conquest accessibility with Blitz, but balance isn’t great, some spec and most healers are way too OP. Matchmaking and MMR in there is completely bonkers though, and duo queues should have never been a thing.

Delves are the highlight here. Accessible high level gear for solo players, at last.
There are still many annoying bugs around.

Gearing overall should receive another pass. Heroic dungeons/LFR/M0/M+ has some serious identity/balance issues at this point in time.

Hero talents aren’t really impactful for many specs. I expected way more out of them.

Warband/alt focus came 15 years late IMO, but better late than never, and it still needs some work.

It’s no Legion, that’s for sure, but it seems serviceable enough, like a lighter BfA.
The next patches will be the deciding factor of whether is will truly succeed or stay mid.
At the very least, I don’t think it will be hailed as a bad expansion, unless they pull a WoD.
