Upcoming content of MSEA? (JUMP! trailer added)

I noticed the following on the MSEA website:

1. Experience & Mesos Gained from the monsters: We have received confirmation news from the developers that monsters Experience & Mesos deductions is not a BUG. Here’s the new structure of the monster Drops and Experience gained. The higher the level difference between your Maple Character and the Monsters, you will receive a certain percentage of penalty.

Note:
– If the difference level between your Maple Character and the Monster is above 21 level, you will receive 60% Deduction in Experience, 100% No drops in Mesos and 100% No Reward Drops ( *Example : Weapons / Equipments / Scrolls ).
– Rewards Drops does not include Monster’s ETC and Potions.
– All boss monsters and normal monsters above level 150 will not be subjected to the reduction penalty.

Didn't do they something like that in KMS as well a while ago?
And did they ever remove those penalties in KMS?

Since EMS is basically a copy paste of MSEA I guess this will be coming to EMS as well :/
And best of all for EMS is that they will probably screw us over even more by not taking over MSEA's SP Reset Scroll Event, they basically did the same with the Chaos patch, copy everything from MSEA except the SP Reset Scroll Event...
