So I just did Stone Vigil for the first time. The members I was paired up with were helpful, but a bit rash at times because they said I didn't use Flash enough. So if I can hold aggro by using Flash initially then by using the Rage of Halone combo, is there really a need to spam Flash? Watching the meters I can do damage and still hold aggro off everyone.

It seems Halone can decrease the aggro better than Flash does anyways.
