Th thorn was nerfed before. The things you are complaing about already got nerfed. It does not need any unnecessary nerfs. Find a weapon or ability to counter it and you'll be fine. It doesn't need to be nerfed. The burn perk is its special perk, if that gets taken away then it becomes nothing more than a different looking legendary hand Cannon. It is an exotic weapon from an exotic bounty. It is supposed to be strong.
