I realized the damage over time is increased, as I watched a Torgue Bulletstormer melted away when I reloaded my gun. I was playing in UVHM.
But is it really?
I checked the gun card info. The DoT damage on card of Maliwan SMGs never surpass the impact damage, the only one comes near the impact damage was Hellfire. Now I have a regular blue corrosive Maliwan SMG and it got 6000 DoT damage, and 4800 impact damage.
Am I missing something? I don’t see it mentioned in the latest update information.
