I'm not really sure, what the requirements are. I think it's recommended level minus X levels, because with my level 60 Asuka i can access 6-4L (recommended level 61-78).
So how does the new system work?
To unlock stages you must have a certain level now, i.e. if you are level 12 you can go up to 2-4H, but even when you beat that stage, you do not unlock 2-5H, because your level is too low. So going to Closed Mine with a level 1 character isn't possible anymore, but that doesn't mean you're leveling up much slower now. At X-5 and X-10 there's an additional NPC with a few quests, which give a lot of xp (about a level up for each). At a certain pont it's basically:
1) Finish genos and additional quests at X-10.
2) Go to X-5 of the next EP, trade in the quests and get a new weapon.
3) start over with 1)
