This update has also made some tweaks to early endgame scaling; a new stat ceiling for all tiers ensures a lower level of difficulty level for downscaled players with a combat rating of 15 higher than enemy NPCs and a greater grading benefit for players who are being scaled down in omnibus content. The player who are scaled up for On Duty missions has new benefits including a damage buff in two players, a 4 player, a 8, and a blockable health if 50 percent is less. source: official forums.
