Hm... Water Spirit thoughts.
The class is always greener on the other side.
Based on absolutely nothing but pure self-speculation…
I’m guessing neither will count. Having regen count would be way too much sustained bar building and promote passive play a bit too much. Pop Water Spirit, pop a few Shouts, and then just sit and let your bar fill on its own like nothing.
The procs from Water Spirit feel like they SHOULD count, but I have a feeling just based on how they work that having them actually count is going to be too difficult to program and keep track of. I’d be happy to be proven wrong, though.
