I'll preface this by saying that I understand the utility of damage auras, and that this is entirely just a grievance from the fact that their placement at the moment locks half the Scrapper sets that even get a damage aura into being forced to take it.
And honestly that could be the full post! I feel that most of the damage auras, in nearly every case, are a suggestion rather than a hard and fast requirement for a set, and that most of their benefits are purely for mechanical tank classes, such as Brutes and Tankers, who can reliably use them to keep aggro. That being said, can we just bump them up to a t3 instead of a t2 so I don't have to keep taking Death Shroud on a Scrapper?
I know it would require an adjustment to pretty much every set except for Ice Armor at this point, but man if it isn't just some real beans having to take this power I'm absolutely not going to slot instead of another resistance toggle that I'm actually going to use, and which will be overall more useful in the early game anyways.
