In concept I can get behind this, in reality seeing what I have seen with stackable passives and synergies in PvP this would make WW so OP it would be redonkulous.

WW Sorc Emp @ full stack would melt the entire buff server and stay in WW until there was 0 AP left to farm.

The long standing suggestion is to change the werewolf form from an ultimate to a toggle, though I don't really think that would work simply because of how the toggle mechanic works (now obviously they can change it). Once you swap weapon bars (which you basically do when you activate the transformation) all toggles are reset. This doesn't even take into consideration that you would then be forced into keepin the toggle ability somehow locked onto both your werewolf bar and your standard ability bar. Now like I said, with the given mechanics I just don't really see a toggle ability being that viable, instead I'll quote my suggestion I made about 6months ago.

"One idea that I've had for quite some time now is to change the transformation to Werewolf from an Ultimate ability to consuming a weapon slot. The theory behind this is to basically give players another "weapon line" option that would now level to 50 instead of 10, and would have both positive and negative aspects attached to it; and obviously changes to the light and heavy attacks would have to be made so as to not make the transformation too OP. One of the perks to this change is that it would not only allow players to stay in Werewolf form for as long as they like, but would give them the freedom to change as often as they like because they could simply swap between there main-hand weapon set and the Werewolf transformation. One of the potentially negative side-effects to this idea is that it forces the player to decide if they'd rather have 2 standard bars for class and other traditional skills or have 1 standard bar and 1 bar being strictly for Werewolf skills.

Also all current negative side effects of being a Werewolf would remain ie. -50% poison resistance and all Fighters guild abilities give the correct passive trait has been purchased.

Two possible new ultimate abilities could be (numbers are arbitrary and based off my stats at v12 six months ago):

Ultimate - cost 200

Rage - Player goes into state of rage, swinging claws violently and dealing 592 physical damage
Blinding Rage - Player goes into state of rage, swing claws violently and dealing 592 damage; Player gains 40% damage for 6 seconds (50% at rank IV)
Relentless Rage - Player goes into state of rage, swing claws violently and dealing 592 damage; Deal's 75 damage to the target every second for 18 seconds (21 seconds at rank IV)

*or*

Ultimate - cost 75

Call of the Omega - Player gains 450 armor rating for 10 seconds
Call of the Alpha - Player gains 450 armor rating and 450 spell resistance for 10 seconds
Call of the Pack - Player gains 450 armor rating for 10 seconds; Increases allies weapon and spell critical ratings by 10% for 10seconds (15% at rank IV)."


Now the transformation animation might also have to be tweaked to not make swapping super tedious, but I feel this provides werewolves the most justice and overall best balance possibilities.
