Depending on the round, the enemy composition may be different. More majors/less redbars. Sometimes, you'll encounter different enemies to fight against that may require a different approach. Ex: Rushing into a sea of Cabal Legionaries could turn out well, but running into a wall of Cabal Turrets? Might result in the need for a rez.

There are no handicap systems or hidden modifiers to make enemies hit you harder.

Are you seeing differences where enemies are requiring more damage to take down? A redbar dreg in one round taking more shots than another redbar dreg? Throw us videos if that's the case.
