I have spent countless hours on the testing and playing werewolf since beta. In all honesty werewolf became more viable in Pts, yes there is a little bit of work to get it just right. I wear 5 heavy 2 medium. white strike/ravager. Though I have experimented with many other sets on pts.
Many on you have probably seen myself in pts and fought me while I was in forum. But after about 15 hours
in werewolf form this is what I've found.
All of the following are my opinions on the PTS Werewolf, and in all honesty aimed at making the werewolf viable, not op.The Bad 
1. With damage lowered and weakness lowered you really won't get one shot anymore, this being said
@ZOS severely nerfed our two solid forms of damage mitigation/longterm survivability, Roll dodge and block.
2. Range on abilities/attacks seams a little short. Infectious claws, heavy attack, light attack, I have to hit them with my forearms in order for it to register a hit. That being said WW clap/hug animation probably can be shelved.
3. Devour still takes too long (sitting duck) and does little besides refill your timer and top off your health.
4. All of the werewolf abilities are way too expensive The werewolf heal is a little too weak for how expensive it is. This is one of the most expensive heals in the game and does little heals 3.5k
5. Werewolf lacks a strong mitigation/utility ability/self preservation ability/purge;
A. Nightblades can cloak to avoid damage
B. Templars have strong self heals if magica/ eclipse
C. Sorcs great battlefield mobility with streaks, and strong class damage shield
D. Dragonknight has wings
E. All classes can shield stack (some better than others)
F. All classes have access to vigar/momentum/bloodcraze
G. All classes have access to armor abilities/buffs/dodge chance
6. We lose ultimate after reverting form.
7. Timer is a little too short.
8. Ultimate cost is too high.
9. Fear has a 1 sec cast time.
10. Loss of most class, guild, weapon passives.
11. Little to hard to lock onto a devour
12. Rousing Roar only 4 sec major brutally?
The Good 
1. Damage is perfect and in line with other classes!
2. They are also adding 10k armour and spell spell resistance while in form which stated = roughly 15% damage reduction. This buff is welcome, though won't be the Werewolf's pvp redemption, with how much armor/spell pen that are currently in game.
3. The transformation is faster!
4. The stam regen is only applied only when slotting the ultimate.
5. There is a lot of food for werewolves in the Imperial City and the bodies don't instantly despawn. This doesn't help regular Cyrodiil.
I would like to see fixes and changes are not only ones that would make make werewolf more fun to play, but also more fun to fight.
The Fix 
1. Add poison weakness to human forum as well.
2. Slightly increase range of melee abilities.
3.
Devour now takes about a second and
IS interuptable, has
NO cooldown. Werewolves shouldn't have to sit down to a five course meal to stay in form, we are bloodthirsty, just give us a nibble and the taste of blood. This heals for the same amount but also applies all major recovery buffs for 30sec.
4. Reduce the cost of the ultimate to 150 and allow us to keep ultimate gained while in form. If the later is impossible lower the cost further. Also decrease the cost of werewolf abilities by at least 20%
5. Make werewolf form punishable by death in cities. Justice system
6. Bloodrage also that grants both major evasion and major brutality when taking damage
7. Roar now costs magica and is an instant cast and fears 2 enemies. Rousing Roar now grants major savagery to all allies for 10 sec.
8. Increase base timer by 50%
9. Hercine's Rage now cost stamina, scales off stamina and weapon damage.
10. No stealth, but add detection range increase. (Master hunters right). Whenever I am fighting a nightblade I feel like someone just raised a stick up in the air yells FETCH then proceeds to fake me out as I run around looking for the stick.

What do these changes do for the werewolf?
Having a penalty to human form helps to define our characters, and makes the affliction more of a decision. Changing our devour, gives us another way to heal ourselves in combat and regen adds to our sustain. Adding evasion gives us a unique inactive way to decrease incoming damage. Changing Roar to cost magica and Hercine's Roar to stamina makes sense, as a true utility ability should not derive stats from your weakest resource, without taking too much away from magica inclined werewolves. As of now building up ultimate takes way too much time and when you transform you take too much time trying to eat, and stay in form to truly enjoy it. Let us transform and revert in a fight to suit our will, cheaper and refilling ultimate will
make werewolf a really unique experience.
Your thoughts?

PS
@ZOS_BrianWheeler my werewolf is starving in regular Cyrodiil. I know you sacrificed the deer to the lag gods, Hercine is not happy.
