Not many players can gain this experience because of class based. So blame the class and the game mechanics. Many hour(s) of grinding plays a factors and all the people you need to be in your party. To achieve maximum experience you must have everything,

this is towards luminous only
1)extra bishop(3),
2) kanna to maximize spawn rate
3) EXP accumulative potion
4) MPE yellow exp pot
5) Weapon Attack speed
6) 5 other players on your map (hard to keep people on)
7) battle mage (damage + attack speed)
8) Zero Character card buff Exp%
9) mercedes link skill exp %
10) holy symbol
11) 3 pet with auto gem buff (so you don't need to cast the needed buff and ignore the other buffs)
12) 1 phantom to cast with auto gem buff with speed infusion
13) green mpe weapon attack speed buff.
14) Pendant of the spirit - Thanks @Tigeon for reminding me =P
Also as for luminous, you must stand in a specific spot to hit nearly full map. If you get knock back you lose experience(s).
Mihile link buff skill which give stance makes a big differences.

how does 3 bishop give you more exp for lumi ? isn't having 1 bishop is the same as having 3 unless your a bishop?
