So does the revamped leveling experience only arrive with the release of BoA? Re-subbed, made a new hunter, and to be honest the leveling process is complete ass, at least sub-20 so far. Last couple times I've played has been with a boosted character, so I haven't went from 1-Max in years... have they streamlined it all? Or will I be going through each expansion area?
What you see now is what you get.
You can ignore entire expansions if you want to with the new system, because scaling means you don't really have to go to some places since everything levels with you (to some extent). I don't have the list of what scaling happens where handy but I'm sure it's not hard to find.
