I'm proposing another suggestion to rebalance werewolves in an additonal way: The ability to get a return of an Ultimate portion when leaving your wolf form.
This can be done in a couple of different ways. Not collectively, but as a few example thoughts on how it might be implemented. Of course, this could be compounded with the mechanic already in place that reduces the cost of your ultimate in the first place. The goal is to make both ends meet a little easier, but not to negate any need for building it up again (I'm certainly not asking to be returned with 285 ultimate).
1. A new passive that returns a base amount per skill point applied
_ There may be a number of levels available to invest skill points into, maybe up to five. Each level offers twenty ultimate back when you return to your normal form.
_ A pre-existing passive could offer additional these benefits, making it more valuable to invest in
_ Investing skill points into all the passives can buff toward this as a whole, encouraging players to make use of all passives, if not already. For example, every skill point put into any passive aside from Devour or Bloodmoon (only one rank each) could offer twelve base return, up to a total of 96.
2. A skill morph/Scribing effect that returns a multiplier based on conditional effects
_ Some of the damaging skills could offer this additonal benefit. Since it doesn't affect damage, it could easily be applied to any morph, perhaps with varying base or percentage ultimate returns or between the choices.
_ Killing a certain amount of enemies within a time frame with damaging skills as an invisible stack. For example, a stack effect process that can occur every fifteen seconds, up to ten stacks, each stack returning ten ultimate when unshifting. [Whether or not the stack has a diminishing cooldown can be determined by the timing, be it less ultimate per for an unlimited timer, or more ultimate returned with a ten-second timer per stack]. This was the original start of my idea, and I feel the most appropriately effort-based for such a rewarding mechanic.
All in all, this can make for a more engaging werewolf system as it makes shifting between easier to manage over a longer period of time, allowing for players to utilise your normal form in quicker succession.
These are just a couple of dynamic ways that this system could be implemented. I invite anyone to build upon or offer other ideas.
