As I said in the other thread just now, you shouldn’t be dependent on Vengeance to maintain threat in 5-player dungeons. Vengeance scales slowly and falls off quickly for that reason — we don’t want that to be the system that lets you stay ahead. It’s intended to help with raid scaling, not be a crutch for poor dps.

As we have said several times, we don’t want Prot paladins to fill every GCD. You also shouldn’t need to in order to maintain threat.

If you are having difficulties in PTR or on Beta, please let us know, but be as specific as you can. Who were you losing threat to? What kind of dps were they doing? Was it an AE or single target scenario? How was their gear relative to yours? We’re unlikely to just buff threat generation based on generic “I have threat problems” reports. Specificity is the key here. It could very well be a bug on the side of the tank or the dps that is causing the problem.

Remember that we very recently buffed the threat generation of Righteous Fury (and similar mechanics for the other tanks), so try and base your perceptions on very recent experiences. Things change pretty quickly at this stage. (Source)
