Let's be honest. The destiny community does not take DOT too kindly which is why I think DOT on weapons in PvP shouldn't be a thing. However in PvE, it would add an unerring advantage if applied to weapons. The best way to re introduce DOT in destiny is this. Enemy specific DOT perks that stack like thorn, but of course do more damage since thorn is still y1. Psion Poisoner: "Psions take poison damage for a small amount of time" Phalanx toxicant: "Phalanx take poison damage for a small amount of time" Captains bane: "Captains take poison damage for a small amount of time" This would create a more varied load out since they could be stronger for certain situations. I'd love to know what you think, and maybe if you have an idea to improve upon mine go ahead and let us know.
