From Reddit: NO level sync when entering a dungeon with less that required players!

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.

Awesome, thank you! I know in a certain other MMO with several expansions worth of old content, a favorite pastime of mine was going back through old content for cool armor sets. I appreciate the lack of item level sync. It makes for a non-stressful enjoyable trip down memory lane getting some awesome vanity pieces along the way.

For fun. S&G. nostalgia. It can be enjoyable to be challenged by something you've beaten to death once in a while. Like it could be a lot of fun to go into it as an underwhelming dps and healer duo to prove you can handle it o.o
The main point is not that you must, but that you can, more freedom is better.
