It seems hypersensitivity affects normal realms much more than nether realms. Normal Realm 1000 is level 100k , 800k with hypersensitivity, while Nether Realm 1000 is level 220k, 441k with hypersensitivity.
Raid seems to be bugged. The higher level an enemy is, the higher chance of Raid affecting it. In fact, with Hypersensitivity on, the enemies always go first.
