It's already so easy to level... I mean you could argue that it's hard to find groups on some servers when you're in a weird level range, but it's not like level sync would really fix that.

There's already so few useful places to camp at, why reduce that number even more with level sync?

I think it's just one of those things that sounds great in theory but once you put it in the game it's just not as cool as you thought.
