Greetings,
Just for clarification, using this system will not remove the item drops, therefore you can use this feature to obtain minions, equipment for glamour, and the items needed to upgrade Zodiac weapons.
Additionally, there is no item level sync, so you'll be able to enter content at the highest level and item level.
On the other hand, if you are looking for more of a challenge, then you can use another feature which will sync to the lowest level set for that duty.
The development team is looking forward to seeing how everyone will use these new feature to create your own unique challenges and group events. They plan on using what they see as reference for future development.
