Thank you, I was not aware of the taunt effects overriding -threat. I had been told previously the reason why scrapper provoke was weaker than a taunt from a tanker was specifically the difference in their threat levels. (Not accounting for the number of targets, I mean just on a single target the ability to keep aggro.) I also feel like when I would run super speed on a tanker they had far more issue keeping aggro on groups because of super speed's -threat. I have no proof though, just a feeling and what others had told me.
Thank you for the reply I appreciate it. Though I think leaving out the details of such a change and having it be a vague "we made this the best of both, the end" is kinda silly, I should test and see if it is truly the best of both and conceals as well as invisibility did prior.
