Not all patches have the performance issues this one does, but that is indeed a pretty minor element.
Korthia feels largely unfinished, and this is likely (hopefully?) due to the absurd amounts of time-gating involved with it. For a zone that is supposed to carry outdoor questing for this patch, it’s underwhelming to say the least (though it is pretty to look at in some spots).
Even the cut scene for the BfA face-off felt really unpolished in spots, and not up to the usual Blizzard quality level… but this is a pretty minor point
The overabundance of spots where movement abilities are limited is kind of boring as well (heroic leap / warlock portal aren’t usable in many areas, chains are blocked off, using a glider in certain areas is an insta-kill, etc). None of that is “fun”.
The rest of the dislikes so far for me are just the time gating and associated metering out of power, whether it’s the knowledge tree, or renown, or box of many things, etc. The game has far too much focus on a player retention via IV drip rather than outright entertainment.
One positive from this so far is that Torghast is more fun than it has been. Completion is now a worthwhile endeavor, and there are some new rares / abilities that are pretty interesting as well.
