So I think thorn needs a dot buff because it only does 2 damage. I think it should be 4 because thats 3 dot damage off from the year one thorn which did 7 dot damage which was way too much and 3 dot damage off if you have the one iron lord artifact on which is 1 dot. Also you should buff the dot damage on it because if people want to avoid the thorn they should try and get the artifact which I think you bungie should buff as well. How you can buff it is that if you buff thorns dot to 4 you should buff the artifact to take off 2 dot damage which would make the thorn suck to those with the artifact on which is what the artifact is supposed to do. Those without the artifact would just have to take on the thorns dot.
