Not the same weapon without the DOT. I'm jealous of your Last Word but Thorn is also one of the best PVP hand cannons once you get mark of devourer.So I pulled Thorn out of the vault to play around with and it is oddly satisfying. It probably has to do with the sound it makes and the super small clip. I think I'll level this up to the DoT effect and see how it fares in PvP. I feel it has potential to be good, but not better than my Last Word.
