I am not part of the Developer people but I am a player and I had these Werewolf ideas in mind and I hope they are accepted by everyone who play's as a werewolf and wants to become one.
In my opinion the WW should last much longer, since the werewolf transformation doesn't stay active on it's own. I do understand how it is pretty much like a normal person turning into a straight up predator type deal, but without a good long lasting time then what is the point of using it if it is to short. I actually have 2 ideas for new passive skills that would make it more worth being a werewolf that will also extend our time as werewolf's. The other idea I have would be more skill's that we can choose from so it's not just 5 skills that we have to use with different morphs. Another possible thing that can change is that as a werewolf we should be able to climb in areas where normal people can't so as a werewolf we don't have to search on how to get around mountains or walls we can just climb up it.
The 2 passive skill ideas I have to be able to extend werewolf form is as follows:
Title: Werewolf Disciple
effect 1: for each skill point put into the werewolf skill tree you gain 15 seconds to be in werewolf form.
effect 2: for each skill point put into the werewolf skill tree you gain 30 seconds to be in werewolf form.
This will significantly extend the time you are in werewolf form if players are truly devoted to using the werewolf ultimate and being a werewolf for the majority of the time they are playing.
passive skill 2
Title: Werewolf Hide
effect 1: for each piece of medium armor equipped you gain 20 seconds to be in werewolf form.
effect 2: for each piece of medium armor equipped you gain 40 seconds to be in werewolf form.
passive effect: if it is a piece of werewolf armor set you gain an additional 15 seconds ( both rings, helmet, shoulders, and chest totaling to 75 seconds. )
I do also think that the werewolf hide set should be a crafting set so that we can use it at higher levels as well. Since it is pretty much a really good trait to mix with a werewolf build.
