VE - threat?Follow

The reason that VE causes such large amounts of threat are due to the fact that it's healing the shadow priest AND the rest of the party (in range). So, not only were we eating threat from the attacks on the target but also eating healing threat. And that adds up quickly. In this regard, VE still generates a large amount of threat. It's not nearly as much as it used to generate, though. It's been changed so that it's 25% to the priest and 5% to the party members (instead of 25% to each). Still generates more threat than the attacks themselves generate, but not as much as it used to.

In addition to the fact that VE is healing for less, Shadowform also now has a built-in Blessing of Sanctuary (-30% threat generated). On top of that, tanks are now doing insane threat generation.

I for one have used VE in every heroic I've been in (haven't had a chance to try it in a raid yet), and have not had any issues. I've only gotten close to the tank maybe once or twice, and then I just popped the new-and-improved Fade (drops ALL threat temporarily now) and the tank was able to distance himself from me a bit.

I can't really speak for the levels the OP mentioned (58-79), but at 80 I have had no issues whatsoever with threat and VE. Feel free to use it, but take this with a grain of salt. I would be cautious and keep an eye on threat meters, Omen or otherwise, until you feel comfortable with the amount of threat it generates.
