I like being able to herb while mounted, however jumping between nodes can take a toll on my dragon’s vigor. I think there should be an additional sub-specialization under the Botany tree where the final talent restores a vigor point after picking an herb. Maybe the half-way point could increase picking speed or something.
As it stands, I stopped picking the lesser herbs because they don’t feel like they’re worth the vigor I’d need to regenerate if I stopped to land. With the current price of Writhebark, I’ve even stopped picking elemental Hochenblume.
