It doesn't look like it. I've looked and looked about this feature since phase 2 and even made a couple posts about it. I have no idea if SE is going to add it or not (I have no idea why it's not there but whatever...) but for right now it's only for fate's, dungeons, and primals
It really isn't needed at the moment, because someone who's level 50 can still give their friend full EXP/loot rights who's much lower than them.
I do want level sync in, but until they nerf powerleveling with high level characters, it isn't really needed outside of FATEs/instances.
Meh, I wouldn't call one shotting everything playing with friends. In XI it isn't forced, you can toggle it in the party settings menu.
That's true, and I agree.
But considering how the game mechanics are as of Phase 4, there isn't a need for level sync unless you want to kill level appropriate stuff with level appropriate friends. I think that'd be cool, but who knows if Yoshi-P will see it that way. :D
