Honestly, the ability to play with my friends is way more appealing to me than leveling in lower areas because it's faster. I'm not using Level Sync to level my high class/job, I'm using it to spend time with a friend. Now, I know that doesn't go the same with all players, so yes it will need to be fixed, but in no way should we even chance not having it simply because someone doesn't want a group of people leveling in this area instead of that area.
