Werewolf tanking has long been an inefficient path to tanking. The worst offender being its lack of an inherent taunt - forcing players to use the Tormentor set to give one of the existing abilities (Leap) a taunt.
It is clear from the design of morphs such as pack leader that werewolf is meant to have a more tanky option at its disposal. I think one change that could go a long way toward making the werewolf ultimate worth using as a tank is giving it a taunt morph for one of its abilities.
I have a few suggestions:
* Howl of Despair is rarely taken by DPS, as its benefit comes from groups being able to use the synergy (and thus do more DPS themselves). Making howl of despair taunt would be an easy fix to allow werewolves to have a built in taunt (thus allowing them to use monster sets such as tremorscale in WW form).
* Feral Pounce is a rarely taken ability period as its alternative that increases weapon damage is far more attractive. The second hit on this ability could be turned from an extension of werewolf duration to instead cause a taunt.
Will this change fix everything wrong with werewolf tanking? No, it still lacks external healing, the ability to burn ultimate to buff allies damage with trial sets, and many other things that will keep it from showing up as 'meta' in hard mode trials, but having an internal taunt will make it far more usable in veteran dungeons as well as normal trials.
