I noticed that corrosive does more damage on flesh, then Fire does on robots. Corrosive deals DoT, though Non Elemental have a higher damage. So I was thinking, which is the better all around gun... Non Elemental or Corrosive?
That said, normal damage will be better than corrosive damage all around. The reason why you notice such a massive difference using fire on loaders is because fire gets a 0.1 damage multiplier against loaders, and a 0.4 damage multiplier against other armoured targets, such as buzzards or soldiers. Meanwhile, corrosive only has to deal with a 0.6 damage multiplier against flesh. Both get a 1.75 multiplier toward their weakness. So, overall, corrosive is at least better all around than incendiary is.
