Totally disagree. Vengeance provided exactly 1 benefit, it allowed tank damage to scale as players progressed through content. But it was a totally backward way of doing it, it made tank damage way higher than dps damage at the beginning of tiers, encouraged weird play (standing in fire), made tank swaps difficult, etc.
Now, that benefit is not even needed for 3-4 of the 5 tanks. Monks, Paladins, Druids, and warriors to a degree all prefer dps stats to tank stats, so they are already scaling as they progress in a natural way (i.e. through gear, the same way dps scales). Not to mention the fact that they also gave tanks 500% threat, so there wasn't really a need for great damage scaling.
DKs are the only tanks left that need any sort of help from vengeance to scale their damage as they progress.
Vengeance caused a lot of problems that do way more than scratch the surface of gameplay, they alter it in huge ways. And it provided only a meager benefit, and now provides almost no benefit at all.
