I don’t know if any changes to how quest items were highlighted were made in TWW but there have been a few times where I’ve hard time seeing them because they are so faintly highlighted. The biggest issue I had is one of the quests with the Puppeteer in Azj’Kahet (it’s the one where you have to click on a bunch of different items in the room). The items on the back table were so hard to see that I circled the room 3-4 times before I finally found them (I think this was a combination of the faint highlighting and blending in with the table’s colors).
Would it be possible to make quest item highlights stand out a bit more?
