I’ll try to explain it as best as I can, if that doesn’t work, I’ll make a video.
When you’re fighting a mob and if the mob dies to the first attack in the combo, or second and third even, the following attacks will keep targeting the dead mob even though there are other mobs nearby. This breaks the fluidity of the combat and I don’t recall it happening before the Breach.
I’m not if this occur because of input buffering, but the issue very evident with weapons that have a projectile in their combo string like Molten Clutch.
