I dont know about removing them but the effectiveness is ofthen so strange.
Armor certainly plays a role there.
The voidling fight comes to mind, a bunch of exploding bugs that deal huge damage. Not that it was that hard but since i only had one ranged character i essentially hid my melee characters and used a bunch of consumeable weapons to kill them before they got into range.
didnt realy feel like what this battle was supposed to be like.
