So far in Battle for Azeroth, the highest base item level I have seen on world quest gear is 330 for solo quests and 340 for dungeons. The highest item level I have received from a world quest is a titanforged 350.
What is the highest item level you can receive from a world quest? Also, will the world quest item levels increase as new content is released?
Note: This question was asked during patch 8.0.
