There's also a x2 multiplier if you are leveling your second highest character that's only active if you're subbed (and a x3 multiplier if it's not your top two highest chars).Ohhh.. I didn't really think about it.
There is indeed the double exp bonus for same account level difference, but I didn't think they would put that on the premium tab.
That really answers it.
